[JVM] Feature Request / OAuth's state instead of local backend

[codlab]

It would be better to have the ability to choose between a local backend running when the OAuth is negotiating on the JVM implementation for desktop or a custom state sent to the OAuth args which would help secure the login.

If this is not something which is already currently in some backlog, I plan anyway to fork and implement such in a later future.

Would be amazing to see PR :). But before implementing that if you could also share here how external api will look like, it would be great
