I want to change the group that receives access requests for my sharepoint.com subsite which has unique permissions, see screenshot
I've already read a related question "How to change subsite group access request?" but the answers all begin with breaking inheritance to create unique permissions, and that process sets the group for access control. But my subsite already has unique permissions. Discussion in that answer also talks about re-inheriting then breaking back to unique, but that would be very disruptive for my subsite.
What other options do I have to change the group that receives access requests for my subsite which already has unique permissions?
