I can't seem to find any documentation on getting a report on pending messages in moderation queue. I want to get a list of all the pending messages for all groups.
The closest I found was on this page.
google does not have an api for that. the closest api is the one they released last week but is only for reporting group acrivity: https://developers.google.com/admin-sdk/reports/v1/reference/activity-ref-appendix-a/groups-event-names
