Location queries not working using Third-party Developer access token

Hi, we are trying to query locations using a Third-party Developer access token which is a user from the 3PL main account NOT a customer account. However, we cannot fetch locations and the response is a blank array.

Please advise.

{
    "data": {
        "locations": {
            "complexity": 13,
            "data": {
                "edges": []
            },
            "request_id": "61cd2c3af61f2ef1eef12b60"
        }
    }
}

Update - I managed to use the API successfully to get the locations.

Hello @Edwin!
That is excellent news! Thank you for coming back and letting us know.
Have a nice day!
