The issue you are facing:
I would like to restrict login to members of a specific group that I am returning with the OIDC user info. The groups are already supported by options as explained in the app readme, but I do not see an option to require membership in a specific group. This functionality is present in the Nextcloud Social Login app from which this was forked, so I thought that perhaps it was a hidden config or something.
