How to use @ViewModelInject on a NavGraph-scoped ViewModel?

See original GitHub issue

If there is only ApplicationComponent, ActivityComponent, ActivityRetainedComponent and FragmentComponent, then how do I get a NavGraph-scoped ViewModel with @ViewModelInject from a NavBackStackEntry?

Sounds like this would only work if there’s a custom component definition and the NavBackStackEntry counts as a @AndroidEntryPoint, but that doesn’t seem possible. Just a hunch, though, in the sample I’m looking at I’m not even sure why @ViewModelInject works at all, or how to get additional @Assisted parameters that are not the SavedStateHandle.
