Reply to a message owned by another grant

@ko-lem Thanks for posting, I think you are on the right path. Let me try to clarify:

  • grant.a has two messages: 1) outreach and 2) customers reply (reply_to_message_id)

  • grant.b does not have any messages

So only grant.a can respond using reply_to_message_id since its only in their inbox. So grant.b cannot use the same reply_to_message_id since its not in their inbox.

So what you are saying makes sense.
