Return all users of a domain and their photos with the google API

I have this code in lumen (laravel) that is returned to me by the users of my Gsuite domain (it works correctly), I have all the data of the users in a Json file in the $ users object, there I receive a JSON as this

{

           "fullName":"AAA BBB",
           "givenName":"CCCC"
        }
     },

}

In the Json there is a property that is users.thumbnailPhotoUrl that returns a URL that if I put it in the browser I get a "blue icon" when this user does have a profile picture ... so I do not have Of course, this field is the one I should look for to pick up the profile picture and show it.

The function I use is this

    public function getUsersDirectory (Request $request)
{

    putenv('GOOGLE_APPLICATION_CREDENTIALS='.resource_path('credentials/admin/credentials.json'));

    $client = new \Google_Client();
    $client->useApplicationDefaultCredentials();
    $client->setSubject('[email protected]');

    $scopes = implode(' ', [
        \Google_Service_Directory::ADMIN_DIRECTORY_USER_READONLY
    ]);

    $client->setScopes($scopes);

    $service = new \Google_Service_Directory($client);
    $users = $service->users->listUsers(array('domain' => ['mydomain.com'], 'maxResults' => 500, 'projection' => 'full'));



    $client2 = new \Google_Client();
    $client2->useApplicationDefaultCredentials();
    $client2->setSubject('[email protected]');

    $scopes2 = implode(' ', [
        \Google_Service_Directory::ADMIN_DIRECTORY_USER_READONLY
    ]);

    $client2->setScopes($scopes2);

    $adminService = new \Google_Service_Directory($client);
    $users = $adminService->users_photos->get('[email protected]');

    return $this->jsonOKResponse($users);

}

As seen in this function $ users really returns the list of users and then I make a call to the api that returns this other JSON but I do not know how to show the content of "photoData"
