    {
      // <script type="text/javascript">
      //    // This is not implemented as part of this issue, but put as a reminder of this need.
      //    window.dataLayer = window.dataLayer || [];
      //    function gtag() { dataLayer.push(arguments); }
      //    gtag('js', new Date());
      //    gtag('config', 'ABC');
      // </script>
      type: "script",
      inline: true,
      content: `
        // This is not implemented as part of this issue, but put as a reminder of this need.
        window.dataLayer = window.dataLayer || [];
        function gtag() { dataLayer.push(arguments); }
        gtag('js', new Date());
        gtag('config', '${myGTagID}');
      `
    }
