How to add a Google ADS Conversion tag to fire onclick?

Hey Guys,

Trying to find a way to monitor visitors conversions on Google ADS, but can’t find a way to add this information in the plugin. Can somebody help me?

<!-- Event snippet for WhatsApp_Clique conversion page
In your html page, add the snippet and call gtag_report_conversion when someone clicks on the chosen link or button. -->
<script>
function gtag_report_conversion(url) {
  var callback = function () {
    if (typeof(url) != 'undefined') {
      window.location = url;
    }
  };
  gtag('event', 'conversion', {
      'send_to': '[XXXX-REMOVED]',
      'event_callback': callback
  });
  return false;
}
</script>
