Calendar API - Unauthorized

Description
I have created a Zoom App, and authorized my account with it in Local test. When I try to get my calendars list, I am getting UNAUTORIZED error, even though I have the required scope. I tried with Postman collection too, it’s still the same.

Error?

{
    "error": {
        "code": 401,
        "errors": [
            {
                "appCode": 0,
                "domain": "global",
                "message": "Failed to pack result",
                "reason": "unauthorized"
            }
        ],
        "message": "Failed to pack result",
        "reqId": "ZMAIL_17a434e9833b7632517826e9b87b9885",
        "status": "UNAUTHORIZED"
    }
}
