I have a Rails 8 app that I am building mobile apps for using Hotwire Native. I already changed the color of the bottom tab bar on Android, and I want to change the top navigation ActionBar color. The ActionBar is added as part of the Hotwire Native package and MainActivity inherits from HotwireActivity, so I don't see it referenced in code. Is there a way to grab the existing ActionBar and change it's color?
