Hi everyone!

I’m trying to use the Master Account API endpoints and getting the following error:  
an example URI: `GET https://api.zoom.us/v2/accounts`

```auto
{
    "code": 124,
    "message": "Invalid access token."
}

```

The app is listed under the Owner account (Business plan) and I’m using _Server-to-Server-OAuth_.  
The app has the right scope permissions to use these endpoints.

Thanks for helping!
