              Admin Reviews in Dashboard
                         ↓
                 ┌───────┴────────┐
         Approve (admin)    Reject (admin)
                 ↓                ↓
      approval_status      approval_status
         = 'approved'         = 'rejected'
                 ↓                ↓
      Visible on store    Hidden from store
