How do I share Google photos?

I would like to have all shared albums of a certain google account automatically into a Drupal website. I was able to establish a connection with 'Google_photos_api' and show all shared albums on site with code below.

<?php
$GooglePhotosService = \Drupal::service('google_photos_api.client');
try {
  $optParams=array("pageSize" => 50);
  $SharedAlbumlijst = $GooglePhotosService->googleServicePhotosLibrary->sharedAlbums->listSharedAlbums($optParams);  
  ksm($SharedAlbumlijst);  
  echo '<div id="GooglePhotos" class="grid views-view-grid">';
  echo '<div class="row">';  
  foreach ($SharedAlbumlijst as $album) {
    echo '<div class="col-6 col-sm-6 col-md-4 col-lg-4 col-xl-3" style="margin-bottom: 10px;">';    
    // Get some properties of an album
    $albumId = $album->getId();
    $title = $album->getTitle();
    $productUrl = $album->getProductUrl();
    $coverPhotoBaseUrl = $album->getCoverPhotoBaseUrl() . '=w200-h200-c';
    echo '<h5>' . $title . '</h5>';
    echo '<a href="' . $coverPhotoBaseUrl . '" id="' . $albumId . '">';
    echo '<img src="' . $coverPhotoBaseUrl . '" alt="' . $title . '">';
    echo '</a>';
    echo '</div>';
  }
  echo '</div>';
}
catch (Exception $e) {
  ksm($e);
}

The problem I cannot figure out is to list all media-items of a given album. Code below is not functioning. I don't know how to pass the albumID into this??

<?php
$GooglePhotosService = \Drupal::service('google_photos_api.client');

try {
  $albumId = 'ANfpKL0unQw8nWACRpVCPj0JxmZ5JHkX_xCecI-VPFxKrFScPPfpE8HakFWvKG3KFVXNnNyigXB0';
  $optParams = ['albumId' => $albumId];
  $mediaItems = $GooglePhotosService->googleServicePhotosLibrary->mediaItems->search($optParams);

  ksm($MediaItems);
}

catch (Exception $e) {
  ksm($e);
}

Any help would be great!! Thanks in advance!!

Error code:
The website encountered an unexpected error. Please try again later.
TypeError: Argument 1 passed to Google_Service_PhotosLibrary_Resource_MediaItems::search() must be an instance of Google_Service_PhotosLibrary_SearchMediaItemsRequest, array given, called in C:\Xampp2\htdocs\Demertr\modules\contrib\php\php.module(81) : eval()'d code on line 7 in Google_Service_PhotosLibrary_Resource_MediaItems->search() (line 79 of vendor\google\apiclient-services\src\Google\Service\PhotosLibrary\Resource\MediaItems.php).

MediaItems.php

class Google_Service_PhotosLibrary_Resource_MediaItems extends Google_Service_Resource {

public function search(Google_Service_PhotosLibrary_SearchMediaItemsRequest $postBody, $optParams = []) {
    $params = ['postBody' => $postBody];
    $params = array_merge($params, $optParams);
    return $this->call('search', [$params], 'Google_Service_PhotosLibrary_SearchMediaItemsResponse');
  }
}

SearchMediaItemsRequest.php

class Google_Service_PhotosLibrary_SearchMediaItemsRequest extends Google_Model {
  public $albumId;
  protected $filtersType = 'Google_Service_PhotosLibrary_Filters';
  protected $filtersDataType = '';
  public $pageSize;
  public $pageToken;
...

No idea really, but looking at the error message and the docs at https://google.github.io/php-photoslibrary/v1.1.0/classes/Google.Photos.Library.V1.SearchMediaItemsRequest.html (if that is the right version), I would say that you need to create an instance of SearchMediaItemsRequest, set the album id on that object and then pass that into the search method. So maybe something like this based on your code:

$media_request = new SearchMediaItemsRequest();
$media_request->setAlbumId($albumId);
$mediaItems = $GooglePhotosService->googleServicePhotosLibrary->mediaItems->search($media_request);
