Add a dropdown in the filter section on this page https://ogcr-app.dcr.ogcr.tesobe.com/activities (I put a red box around the section in the screenshot) that filters Entity: activity based on the connected Entity: activity_verification status.
The three states should be "All", "Verified", and "Unverified".
All = all Entity: activity
Verified = Entity: activity that are referenced in an Entity: activity_verification that has the status "verified"
Unverified = Entity: activity that are not referenced in any Entity: activity_verification
