Google sheets cell as plain text from the API

Question

I am trying to change cell format to plain text from google api: https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets/batchUpdate

Doing it directly from google drive gives me a completely different result than doing it from the API.

I add the following examples of what I am trying to do.

This is from the spreadsheet formatting:

1. This is the field I want to format as plain text

2. This is what I do

   Format > Number > Plain Text

3. This is the result:

This is what happens when I format it from the google API with the above JSON:

1. This is the field I want to format:

2. This is the XML that I am applying from the API:

        "requests": [
          {
            "repeatCell": {
              "range": {
                "sheetId": 3,
                "startColumnIndex": 2,
                "endColumnIndex": 3,
                "startRowIndex": 16,
                "endRowIndex": 17
              },
              "cell": {
                "userEnteredFormat": {
                  "numberFormat": {
                    "type": "TEXT"
                  }
                }
              },
              "fields": "userEnteredFormat.numberFormat"
            }
          }
        ]
      }```
   
   

3. This is the result of applying the format from the API:

My problem: how can I get the same thing from the API as from the sheet? What do I have to change in the JSON to correctly apply the format?
