Body class if visible

Hello, Great plugin!

I am trying to add a custom body class if the widget is active on a certain page. In my case it is a slider.

add_filter('body_class', function (array $classes) {
    if ( is_active_sidebar( 'slider' ) ) {
		$classes[] = 'slider-active';
	}
  return $classes;
});

This filter adds the class without issue but it is showing on all pages even though my widget is only set to display on the Home/Front. Is there a way I can set it to only show on the pages it is active on by adding a variable to check if the widget option is set to visible?
