You currently can only send a plain text message, or a ChatGPT-based message in the first step, but it would be great to use JSON in the first step (to generate our own texts and send it through DMs).that was one of the main reasons we joined was thinking you can do json step for both comments and dms. we can do for dms but don't understand why that can't be done for comments the same way if we're doing the backend ourselves anyway?
