We have a huge, classic portal, with several SharePoint groups (not O365 groups) for each customer like:
- customerA-Visitors, Members
- customerB-Visitors, Members
The group owners have rights to manage the group, but they don't have manage permissions rights on the portal itself. One person can manage multiple customers. I would like to give them an interface to add/remove members to groups, like "Groups I own". I found workarounds, how to edit the view of the user information list and add extra fields, so I could apply a filter, but unfortunately the "Owner" is not there. How can I create such an view?
