Is there some kind of pattern in Compose to execute actions inside nested components without exposing too much details outside? In my specific example I have a LazyColumn somewhere deep into a more complex component, and I want to expose an action like “scroll to top” to the outside world. Obviously, I don’t want LazyListState to be exposed, because composition of this bigger component can change, but semantic would remain. How do you do this?

You can create your own state class, e.g. MyComponentState, and expose a function such as scrollToTop().

And how the function would be implemented? Consumer of MyComponent would need to rememberMyComponentState() and pass it down, and without knowing the internal structure how it would hook in?

Yep. You can just hold a LazyListState as an internal var and call LazyListState.scrollToItem() in scrollToTop().
