Gravity Forms Elements Trigger Configuration

The following block of code is a listener for Gravity Forms submissions. Prior to using Generate Press, we used to run this directly in Tag Manager with a DOM Ready trigger. But that no longer works for us, and I realize that we probably should set this up as an element.

Would appreciate guidance for the hook configuration to use this.

<script type="text/javascript">
  jQuery(document).ready(function() {
   jQuery(document).bind("gform_confirmation_loaded", function(event, formID) {
    window.dataLayer = window.dataLayer || [];
    window.dataLayer.push({
     'event': 'formSubmission',
     'formID': formID
    });
   });
  });
</script>
