Whenever using the delete option on a message not belonging to the current user, it does not work.
Steps to reproduce
Try to delete a message from another user, the option to delete it is proposed, the confirm modal appears, but no action is done.
The user trying the action is an administrator of the team/channel
Really doing the delete action, or at least, do not propose it if not possible/intended to work this way.
No error message and no deletion of the message.
