Bug/support - cannot load extensions page

[ORESoftware]

I have this:

   chromeLauncher.launch({
      enableExtensions: true,
      startingUrl: 'chrome-extension://idbanmbeeadlaanhdemgngeooobbadde/dist/index.html'
    })
    .then(chrome => {
      console.log(`Chrome debugging port running on ${chrome.port}`);
    });

I get this:

any idea why it can't load the extension's page?

by the way, I am trying to open it in a new tab in an existing window, but it keeps opening in a new window, let me know if there is some way to try to force it to use a tab instead of a new window. thx.
