Not working

[Navds]

Or maybe I missed something in the installation.
Slack 3.2.1 64-bit on Linux
Here is what I did:

1. Added the js at the bottom line of /usr/lib/slack/resources/app.asar.unpacked/src/static/ssb-interop.js

  ...............................................................................
  const resourcePath = path.join(__dirname, '..', '..');
  const mainModule = require.resolve('../ssb/main.ts');
  const isDevMode = loadSettings.devMode && isPrebuilt();

  init(resourcePath, mainModule, !isDevMode);
}

// First make sure the wrapper app is loaded
document.addEventListener("DOMContentLoaded", function() {

   // Then get its webviews
   let webviews = document.querySelectorAll(".TeamView webview");
   ...............................................................................

2. Restart Slack
