Help with Google API Client Wrapper

I am hoping that someone can help me with the Google API Client Wrapper package from pulkitjalan/google-apiclient (https://github.com/pulkitjalan/google-apiclient)

We are a Google Suite organization and I am trying to use the Directory Service to return data about ChromeOS Devices that are enrolled in our organization.

So far I have the following which seems to be working:

 $config = config('google');

    $scopes = [
        'https://www.googleapis.com/auth/admin.directory.device.chromeos',
    ];

    $googleClient = Google::getClient();
    $googleClient->setSubject('[email protected]');  // 
    $googleClient->setAuthConfig($config['service']['file']);
    $googleClient->setAccessType('online');
    $googleClient->setScopes($scopes);

    $directoryService = Google::make('directory');
     dd($directoryService);
  

Which returns the following:

}

I need to run a query using my customerID and the device serial number and have it return a the ChromeOSDevice object with the necessary data about that device similar to what is available here: https://developers.google.com/admin-sdk/directory/reference/rest/v1/chromeosdevices/get

I just don't know where to get started with this package as there aren't many examples to get me oriented.

Thank you
