I realize this is outdated now, but have you ever had luck with the navigationBarColor property? I can't seem to get it to work, and I'd like to make the navigation transparent for my main view in my TWA on Android 10+, as described here https://medium.com/androiddevelopers/gesture-navigation-going-edge-to-edge-812f62e4e83e
