Custom function to pass in a jQuery script to set a cookie via manual JS during 'on_click' trigger event and on form close.

Set Cookie on Form Submit and Close

<?php

add_action( 'wp_footer', 'my_custom_popup_scripts', 500 );

function my_custom_popup_scripts() { ?>
<script type="text/javascript">
      (function ($, document, undefined) {
        
          jQuery('#pum-1483').trigger('pumSetCookie');
        
          setTimeout(function () {
              PUM.close(1483);
          }, 5000); // 5 seconds
        
      }(jQuery, document))
</script><?php
}

@strarsis the the popupElement you pass in gets passed to PUM.getPopup(). That is a magic function of sorts and will accept an element, a numeric ID #, or a selector. So you could probably shortcut and just do PUM.setCookie(<id>) similar to the example aboves PUM.close(1483)
