I'm looking for an "easy" way to get the inviting "object" (user, app, ...) for an B2B user object (userType -eq "guest"). The only information available regarding this typ of data is the Azure AD audit logs. But I really would like to avoid checking the audit log for the specific user object. The retention period and also the delay until the data is available in the audit log are some big pain points.
I've checked serveral docs regarding B2B invitation/redemption but without luck. I really would love to see an property on the user object like invitedBy:GUIDofINVITINGuser
