I am trying to create a communication channel between tabs. In my main tab I have the following:

window.addEventListener("message", (event) => {
   console.log(event.data);
}, false);

I am opening new tab using this code:

window.open('https://localhost/newtab.html', '_blank');

In the newtab.html I hav this code:

<html>
  <body>
    <script>
        window.postMessage('message', 'abc');
    </script>
  </body>
</html>

Both target tab and new tab are on the same domain. I am not getting into target tab when opening a new tab. What am I missing?

Thanks
