add & remove class wpc-opened

Hello

Kindly note that I customized the filter everything plugin to the following
https://allbrandsfactoryoutlet.com/new/product-category/2-women/

but I have problem when I click to the filter button the content section opened but it’s not close when I click outside the box so I added the following code to fix this issue

<script>
	jQuery(document).on('click', 'body', function(e) {
    if (!$(e.target).is('.wpc-filter-title button'))
      $('.wpc-filters-section').removeClass('wpc-opened')
		.addClass('wpc-closed');
  });
</script>

it’s working fine but it’s not covered all the button it’s working when you click up of the arrow could you please help me to fix it ?

Best regards
Rawaf
