Hi @pipinstalled, thanks for the work.
In my opinion, we are repeating ourselves by having the send_messages function.
This function duplicates the logic of send_message, which goes against the DRY principle.
We could use the same function but extend it to accept either a single MessageSchema or a list of them.
This way, it would be simpler for users as well.
