If you are the admin of a group chat, and you are leaving a group chat:
- If you are the only admin of that group chat, a random member will be assigned as the new Group Admin
- If there are more than one admins in a group chat, your admin rights will be revoked.
If you are the only admin, you can make a member admin of the group before leaving the group. To know how to share the Admin rights, click here.
