Gmail sidebar gadget using Google Apps Script > Refused to display

I have a simple Google Apps Script project as follow, published as a web app

Code.gs

function doGet(e) {
  return HtmlService.createHtmlOutputFromFile('Button1');
}

Buttom1.html

<html>
  <script>
    function myFunction() {
      var response = "Ok, Done" // do something that returns "Ok, Done" response
      var b = document.getElementById('result');
      b.innerHTML = response;
      document.getElementById('button1').disabled = 'disabled';
      return;
    }
  </script>
  <body>
    <button onclick='myFunction()' id='button1'>Do IT Now!</button>
    <div id="result">Ready ...</div>
  </body>
</html>

Within Gmail > Settings > Labs > I enabled "Add any gadget by URL" and add a link to the following xml file representing a sidebar gadget associated with above web app project

<Module>
  <ModulePrefs title="Testing -GAS" />
  <Content type="url" href="https://script.google.com/a/macros/thexs.ca/s/AKfycbxvL43dfxJb82wxRST1bXIf08gSrVlbKt1W4Uxvy0QSq-SxFTA/exec" />
</Module>

I can only see the title of this gadget because Chrome is refusing to display the App in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.

Also note in the error message below, that there are a bunch of parameters added to the Url.

I know it's doable and probably trivial, but have No idea on how to fix this problem.

This is the error in the Chrome console:

Refused to display 'https://script.google.com/a/macros/thexs.ca/s/AKfycbxvL43dfxJb82wxRST1bXIf08gSrVlbKt1W4Uxvy0QSq-SxFTA/exec?container=gm&view=default&lang=en&country=CA&sanitize=0&v=6c3c95f52b62fa08&rpctoken=g5ik00zemwti&libs=core%3Aauth-refresh&parent=https%3A%2F%2Fmail.google.com%2Fa%2Fthexs.ca%2Fhtml&pid=thexs.ca&mid=0&st=e%3DAA6WCYb%252F6JLIjQyyLJLyGaZcTWLgsk3YtjB0AWV9dNYxEmbptJBGKM5uhcb8yYlaL2%252FGk7M4%252Fu%252B1WJJgprkAjjlNELAYOoNkcAXOb9X4w%252B721DtB0RR%252FawL2Eo9%252BHSMp97FE6sy1kXk5%26c%3Dgm' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.

Google Apps Script Web Apps can currently only be inserted into Google Sites as gadgets because of cross domain restrictions on iframes. There is an open issue ticket for this with more details and an opportunity to detail your use case
