 * Send Message to Channel
5 
 * Post a message to a channel, DM or group DM by ID. Pass `thread_ts` (the parent message's `ts`) to reply in a thread, and `blocks` to send a Block Kit layout — `text` is then the notification fallback. Returns the posted message's `ts`, needed to update it or react to it. Needs chat:write; a bot token posts to public channels it is not in only with chat:write.public.
