Do a best effort implementation even if it might not be possible to create a solution that is as good as it is on Windows.

For macOS it's easy i think and no need of native module (if i remember correctly).
But i wanna do the same for windows and mac too in future!

Yes actually I just found in the docs that you can specify that type: 'desktop' for Mac, it works perfectly!
