Integration with google's suppoer navigation library

Google has magical support with their own implementation of navigation library and their own bottom nav bar via this simple method:

> NavigationUI.setupWithNavController(bottomNav, navController)

Since their bottom navigation implementation is so terrible and missing many features it would be nice to use ahbottomnavigation. Is it possible to create some helper method for similar connection to navigation library - my current hacky solution is terrible right now :)

Start by reviewing the mentioned NavigationUI.setupWithNavController(bottomNav, navController) entry point and how ahbottomnavigation currently connects to a NavController. Compare that integration with the requested helper method and define completion as a supported connection to Google's navigation library without the reported hacky solution.
