Is there something like onBackPressed listener? I want to override onBackPressed to make sure I don't navigate back in certain cases

Key input is subject to various key event dispatch and focus rules that can cause the events to be missed. The androidx OnBackPressedDispatcher is the preferred way of doing it these days; if you poke around the jet* samples you can see a few copy/pastes of basically this gist: https://gist.github.com/adamp/62d13fe5bf0d6ddf9fcf58f8a6769523

the style in there is a bit dated but you get the idea 🙂 use Providers up near your initial setContent or whatnot to provide the OnBackPressedDispatcherOwner and you're good to go

Got it. Thanks!

AmbientBackPressedDispatcher isn't supposed to be private right?

Up to you. I pulled this out of an app I was writing where it was in the same file I was providing it from 🙂
