Problem/Motivation

I had created a view with a page display and had configured grouping by field.
And now I want to implement preprocess hook to handle classes for group title wrapper. But unsuccessfull.
Here example:

/**
 * Implements hook_preprocess_HOOK().
 */
function my_module_preprocess_views_view_grouping(&$variables) {
  \Drupal::messenger()->addStatus('Hook triggered');
}

Looks like hook doesn't triggering.
