Error when trying to use \Drupal::service('cloudinary_media_library_widget.asset_generator') in 'drupal/cloudinary:^3.0@RC'

Error when trying to use \Drupal::service('cloudinary_media_library_widget.asset_generator') in 'drupal/cloudinary:^3.0@RC'

I tried below code in my custom module from Cloudinary image with programmatically →

$value = 'cloudinary:image:upload:cld-sample-4';
$tag = \Drupal::service('cloudinary_media_library_widget.asset_generator')->getBaseTag($value);

// Returns tag with generated asset url.
$html = (string) $tag
->resize(Resize::fill()->width(400))
->format(Format::auto());

And i got this error

The website encountered an unexpected error. Try again later.
