Google appscript does not recognize Chromium based Edge

I am trying to detect Chromium based Edge browser in google slides addon.

Code.gs

function onInstall(event) {
    onOpen(event);
}

function onOpen(event) {
    SlidesApp.getUi().createAddonMenu()
        .addItem('Open the sidebar', '_showSidebar')
        .addToUi();
    _showSidebar();
}

function _showSidebar() {
    var ui = HtmlService
        .createHtmlOutputFromFile('index')
        .setTitle('Test add-on');
    SlidesApp.getUi().showSidebar(ui);
}

index.html

<html>
  <head>
    <base target="_top">
    
    <script>
       const onButtonClick = () => {
         console.log(window.navigator.userAgent);
       }
    </script>
  </head>
  <body>
    <button onclick="onButtonClick()">Click me</button>
  </body>
</html>

Clicking on the button in sidebar logs to console:

5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.105 Safari/537.36

But when I manually type window.navigator.userAgent to browser console log looks differently (Edg/84.0.522.49 is missing):

5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.105 Safari/537.36 Edg/84.0.522.49
Solution

  • The main problem is that your Google Slides addon/sidebar is running inside an iframe which is hosted on docs.google.com.

    The new Chromium based Microsoft Edge browser overrides User-Agent on some sites to maximize compatibility. If you open edge://compat/useragent in your Edge you will see that the docs.google.com is listed in that "User agent overrides" list: enter image description here

    To disable the user agent overrides functionality, you may run the Microsoft Edge executable using the following command line argument: --disable-domain-action-user-agent-override
