Smooth Scrolling Not Working even though the option is enabled.

Hi,

So on I have this issue on the site i linked below..

The smooth scrolling isn't working, even though I have the option enabled from Customize >> General

and also added

add_filter( 'generate_smooth_scroll_elements', function( $elements ) {
  $elements[] = 'a[href*="#"]';
  
  return $elements;
} );
