Thanks for this, would you mind adding a simple spec to spec/api-browser-window-spec.js for this that just verifies it does not crash or throw unexpected errors?

Something like but with valid values for all the supported keys:

it('supports setting the app details', function () {
  assert.doesNotThrow(function () {
    window.setAppDetails({appId: 'my.app.id', relaunchCommand: 'electron'})
    window.setAppDetails({})
  })
})

Also, can you update the docs in docs/browser-window.md with the usage details?

Thanks for the suggestions. I've updated those files.

Thanks for adding this, apologies for the delay getting it merged 🚢 👍

Thanks!

Heads up: this doesn't seem to do anything anymore #16087 @the-ress
