Is it currently possible to delete a message from a channel, using the Graph REST API?
I can retrieve a message with GET:
GET /teams/{team_id}/channels/{channel_id}/messages/{message_id}
But the corresponding DELETE fails with a 404 error:
DELETE /teams/{team_id}/channels/{channel_id}/messages/{message_id} # fails
I'm using the beta API, if it matters. I'm also the author of the message in question.
