channel_thread_message_start

Creates a new thread from an existing message. Returns a channel on success, and a 400 BAD REQUEST on invalid parameters. Fires a Thread Create and a Message Update Gateway event.

When called on a GUILD_TEXT channel, creates a PUBLIC_THREAD. When called on a GUILD_ANNOUNCEMENT channel, creates a ANNOUNCEMENT_THREAD. Does not work on a GUILD_FORUM or a GUILD_MEDIA channel. The id of the created thread will be the same as the id of the source message, and as such a message can only have a single thread created from it
