On the General tab, It’s also possible to assign admins to become Group Managers of a group. By default, All admins can update or delete a group. If you want to assign Specific admins to become Group Managers, switch the group managers setting from All to Specific, click Add managers and select the admins from the dropdown list. When you assign Specific admins to become Group Manager of a group, only these people will be able to update or delete the specific group.
