After following setup, getting 403 error on basic test in editor

[ConnKing]

I ran through the setup guide and tried the .json OAuth 2.0 Client ID files for both Desktop and Web application with http://localhost listed in under my Authorized redirect URIs.
The values seem to be getting set correctly in the window

Then on start I call:

 void Start()
    {
        // Listing files.
        GoogleDriveFiles.List().Send().OnDone += fileList => {
            var files = fileList.Files;
            foreach (var f in files)
            {
                Debug.Log(f);

            }
        };
}

When I click run in the editor with the script attached to a GameObject in the scene. It gives me this error:
UnityGoogleDrive: HTTP/1.1 403 Forbidden
Google Drive API Error Description: Code '403' Message: 'The request is missing a valid API key.'
- Domain: 'global' Reason: 'forbidden' Message: 'The request is missing a valid API key.' LocationType: '' Location: ''

the uri listed with the error is https://www.googleapis.com/drive/v3/files

Is there something I'm missing? Any help would be appreciated.
