I have the following doc stored in MongoDB:

```
{
    "_id": 2,
    "template_name": "AllahabadBank",
    "description": "Form For NewCustomer Application In Banking System",
    "handwritten": "true",
    "file_path": "./serverData/batchProcessedFiles/AllahabadBank/input",
    "annotated_data": [{
        "page_num": "page-01.jpg",
        "entities": [{
            "label": "CIFNo",
            "type": "text",
            "boundary_box": {
                "x1": 325,
                "x2": 861,
                "y1": 324,
                "y2": 360
            }
        }],
    "num_of_pages": 12
  }]
}

```

And want to insert below JSON data to **annotated\_data**. Suggest me MongoDB query or Python Code to perform this.

```
{
  "page_num": "page-02.jpg",
  "entities": [
    {
      "label": "CustomerName",
      "type": "text",
      "boundary_box": {
        "x1": 559,
        "x2": 1615,
        "y1": 382,
        "y2": 440
      }
    }
  ]
}

```
