I do request - https://api.monday.com/v2
with body:

{"query": "query { items_by_column_values 
  (board_id: *, column_id: \\"status8\\", column_value: \\"Upload\\") 

  { assets {url, public_url} column_values {  text title }}}"
}

In response I have:

{
  "data": {
    "items_by_column_values": [
      {
        "assets": [
          {
            "url": "*/resources/*/MicrosoftTeams-image%20%2835%29.png",
            "public_url": "*/resources/*/MicrosoftTeams-image%20%2835%29.png"
          }
        ],
        "column_values": [
          {
            "text": "*/resources/*/MicrosoftTeams-image%20(35).png",
            "title": "Files"
          }
        ]
      }
    ]
  },
  "account_id": *
}

I expected MicrosoftTeams-image%20%2835%29.png or MicrosoftTeams-image (35).png, but received - MicrosoftTeams-image%20(35).png in data.items_by_column_values[0].column_values[0].text
