+- Displayed members' name instead of default AI chatbot channel name, like the `Group Channel` does.
 - Fixed an issue where editing a text parent message in a channel did not update the corresponding parent message in the Thread area in real-time.
 - Fixed a GroupChannel UI error when the `Open in Channel` action is triggered in a different channel.
   * The `Open in Channel` implementation invokes both `setCurrentChannel` and `setStartingPoint`.
