Need an admin Funktion

This App is great, I really enjoy using it and its features. But I can not rate 5*.
Due to my gaming Apps I am using the Group-Chat feature alot.The maximum amount of group members possible made me switch from WhatsApp but I am missing something to set admin rights since some people think it is funny to nuke chats meaning they delete all members and make it a pain to keep groups running.
It would be kindly apreciated if you could ad a feature to set certain rights within the groups.
It would make the use of your App alot better!
Thankyou!
