  A service handling in-experience text chat, including
  `Class.TextChannel|managing channels`, decorating messages, filtering text,
  `Class.TextChatCommand|creating commands`, and
  [developing custom chats interfaces](../../../chat/examples/simple-custom-frontend-ui.md).

  To learn more, see
  [TextChatService Overview](../../../chat/in-experience-text-chat.md).

  For further customization, TextChatService has the following singleton
  children:

  - `Class.ChatWindowConfiguration`
  - `Class.ChatInputBarConfiguration`
  - `Class.BubbleChatConfiguration`
  - `Class.ChannelTabsConfiguration`

      Each of the default channels has the described special behavior applied to
      messages using its internally bound `Class.TextChannel.OnIncomingMessage`
      callback function, changing how messages appear when sent through the
      channel. The callback is assigned automatically either at runtime (if the

      Note that the default `Class.TextChannel.OnIncomingMessage` callbacks can

      `Class.TextChannel|TextChannels` even if

      Messages from different TextChannels can be separated into different tabs
      in the chat window using `Class.ChannelTabsConfiguration`.

    description: |
      Determines whether a user has permission to chat directly with other users
      in experiences based on their parental control settings. To be used when:

      - The line of communication is user-initiated (not developer- or
        gameplay-initiated)
      - Access to the communication is closed and limited

      An example of a direct chat is a whisper channel between two users.

      You may use this method to gate certain features in your experience
      depending on the result.

      When creating a `Class.TextChannel` for a direct chat, use
      `Class.TextChannel:SetDirectChatRequester` to set the requesterUserId so
      that the channel can determine whether to deliver messages between users.
      When `Class.TextChannel.DirectChatRequester` is non-nil,
      `Class.TextChannel|TextChannels` internally use this result to determine
      whether to deliver messages between users.

      ```lua
      local whoCanDirectChat = TextChatService:CanUsersDirectChatAsync(requesterUserId, { userId1, userId2 })

      if #whoCanDirectChat > 0 then
        -- The requesterUserId can direct chat with either userId1, userId2, or both
      else
        -- The requesterUserId cannot direct chat with either userId1 or userId2
      end
      ```

      Note that this method is only available for use in a `Class.Script` with
      `Class.Script.RunContext|RunContext` of `Enum.RunContext.Server` or
      `Enum.RunContext.Legacy`.

      Called when a bubble chat is about to be displayed. This can only be

      Use this to customize individual bubble chat messages. If this callback
      returns a `Class.BubbleChatMessageProperties`, those properties will be
      applied to the associated bubble, overriding
      `Class.BubbleChatConfiguration` properties. If a `Class.UICorner`,
      `Class.UIGradient`, or `Class.ImageLabel` is parented under
      `Class.BubbleChatMessageProperties`, they will also override their
      respective counterparts defined in `Class.BubbleChatConfiguration`.

      If the chat message is sent by a player, `message.TextSource` will
      correspond to that player, and `adornee` will be `nil`.

      If the chat message is sent via `Class.TextChatService:DisplayBubble`,
      `adornee` will be the `partOrCharacter` provided, and `message.TextSource`
      will be `nil`.

      When bound to the client sending a message, this callback is run twice:
      first when the message is initially sent and received locally, then again
      when the client receives the result of the filtered message from the
      server.

      Called when a new message is about to be displayed in the chat window.
      This can only be implemented on the client.

      Use this to customize individual messages that appear in the chat window.
      If this callback returns a `Class.ChatWindowMessageProperties`, those
      properties will be applied to the associated message, overriding
      `Class.ChatWindowConfiguration` properties. If a `Class.UIGradient` is
      parented under `Class.ChatWindowMessageProperties`, it will also override
      the `Class.ChatWindowConfiguration.TextColor3|TextColor3` property defined
      in `Class.ChatWindowConfiguration`.

      When bound to the client sending a message, this callback is run twice:
      first when the message is initially sent and received locally, then again
      when the client receives the result of the filtered message from the
      server.

    description: |
      Called when `Class.TextChatService` is receiving an incoming message. Can
      only be implemented on the client.

      Use this to decorate `Class.TextChatMessage|TextChatMessages`. If this
      callback returns a `Class.TextChatMessageProperties`, those properties are
      merged with the `Class.TextChatMessage` parameter to create a new
      `Class.TextChatMessage`.

      When bound to the client sending a message, this callback is run twice;
      first when the message is initially sent and received locally, and again
      when the client receives the result of the filtered message from the
      server.

      Note that this `Class.TextChatService.OnIncomingMessage` callback runs
      **before** any `Class.TextChannel.OnIncomingMessage` callbacks.

      This should be defined only once in the source code. Multiple bindings
      will override one another in a non‑deterministic manner.

          `Class.TextChatMessage` with those properties, otherwise, if `nil` is
          returned, then `Class.TextChatMessage` is not changed.
