      },
      users_without_field: {
        $sum: { $cond: [{ $ifNull: ["$ai_edit_complete", false] }, 0, 1] }
      },
      avg_ai_edit_complete: { $avg: "$ai_edit_complete" },
      max_ai_edit_complete: { $max: "$ai_edit_complete" },
      min_ai_edit_complete: { $min: "$ai_edit_complete" }

// Note: This converts updatedAt to DD/MM/YYYY format
// Run this carefully as it modifies data
db.media_clicks.find({ 
  ai_edit_last_date: { $exists: false },
  updatedAt: { $exists: true }
}).forEach(function(doc) {
  var date = doc.updatedAt;
  var formatted = date.getDate().toString().padStart(2, '0') + '/' + 
                  (date.getMonth() + 1).toString().padStart(2, '0') + '/' + 
                  date.getFullYear();
  db.media_clicks.updateOne(

  );
})
```
