Alter chat channel owner
The user who starts a chat channel is also the owner.
If this user leaves the company, the chat cannot be altered (adding or removing users)
A moderator or admin should be able to "chown" a chat Channel.

Yes. That is exactly the problem.
If the channel owner (and only admin) leaves a channel, all members of the chat become admin. I guess the only problem right now would be that this is not happening when a user gets deleted / deactivated, right?
