Hi there!
First, I'd like to thank you for this sample app! It seems simple from a functionality point of view, but it provides some helpful examples to solve big team/complexity challenges.

For someone who is doing Android for a while now, but is kind of new to Compose, I'm currently struggling with the navigation stuff. As far as I can see the app has only one screen per feature module. With the provided navigation concept it's fairly easy to navigate between the top level screens. But I have a hard time to figure out how to navigate between multiple screens within a feature module, because I don't have access to the navController within the module.

With the NIA-Navigation concept, how would you solve the following screenflow:
A user can navigate from a home screen to a "Quizz" (that's a no-brainer). The Quizz is a feature module with an

• introduction screen,
• (for simplicity sake) 4 hardcoded question screens
• summary screen

Now, I don't see any reason why the NavHost should handle the self contained navigation within this feature module. IMHO it should only handle navigation between features, but not navigation within features. Doing the navigation within the NavGraphBuilder-Extension functions, e.g. NavGraphBuilder.interestsGraph is per se not possible, because we don't have access to the navController.

The question is: How would solve this? Would you pass the appState to the navGraph extension functions? Or is there a mechanism I'm not aware of?

Thank you for your support!
