Adding a videoask widget to specific pages:

<script>

  // Customise your widget options here
  window.videoask_config = {

    "options": {
      "widgetType": "VideoThumbnailExtraLarge",
      "text": "Talk to me",
      "backgroundColor": "#FF3C4C",

  // Specify the pages where you want it to load
  window.videoask_pages = [
    '/widget',

    '/widget-specific-pages'
  ]
</script>
<script src="https://www.videoask.com/embed/embed.js"></script>

<script>
  let widget = null;

  function handlePageView() {

      if (widget) return;
      window.videoask.loadEmbed(window.videoask_config).then(function (el) {
        widget = el;
      });
    } else if (widget && document.body && document.body.contains(widget)) {
      document.body.removeChild(widget);
      widget = null;
    }
  }

  function locationChecker() {
    var previousPathname = window.location.pathname;
    setInterval(function () {
      if (previousPathname !== window.location.pathname) {
        previousPathname = window.location.pathname;
        handlePageView();
      }
    }, 500);
