Hide cookie banner on specific pages/posts not working

Hi,

I used the filter as described in a mu-plugin:

function cmplz_my_filter_site_needs_cookiewarning( $cookiewarning_required
) {
	global $post;
	
	if ($post->ID==6612)

	{
		$cookiewarning_required = false;

		define('CMPLZ_DO_NOT_BLOCK', true);
	}
	else{
		$cookiewarning_required = true;
	}

	return $cookiewarning_required;
}
add_filter( 'cmplz_site_needs_cookiewarning', 'cmplz_my_filter_site_needs_cookiewarning' );

However, it is not working. Is the filter still working?

The page I need help with: [log in to see the link]
