publish_{$post_type} hook works only for posts and not for custom post types or pages

I’m trying to send push notification when any of posts, custom post types or pages is published. I’m getting enabled post types from the plugin settings and adding action via foreach loop in my class __construct method. The problem is that it only works for posts and not for any of custom post types or pages. Here is my function and action:

foreach ((array)get_option('PushPostTypes') as $postType) {
    add_action("publish_{$postType}",  array($this, 'doNewPostPush'), 10, 2);
}

public function doNewPostPush($id, $post) {
    $pushData = array(
        'title' => $post->post_title,
        'body' => strip_tags($post->post_content),
        'data' => array(
            'url' => trailingslashit(get_permalink($id)),
        ),
    );

    if (has_post_thumbnail($id)) {
        $pushData['image'] = get_the_post_thumbnail_url($id);
    }
    
    $this->sendNotification($pushData);
}

get_option('PushPostTypes') is an array of post types that user choose, for example: array('post', 'page', 'custom_post');

Any idea why it only works for post and not for pages or custom post types?
