How to scroll LazyColumn to the top and display BottomAppBar after clicking a button

This is my simplified code:

val scrollBehavior = BottomAppBarDefaults.exitAlwaysScrollBehavior()
val isCollapsed = scrollBehavior.state.collapsedFraction != 1.0f
val listState = rememberLazyListState()
Scaffold(
    contentWindowInsets = WindowInsets(0, 0, 0, 0),
    modifier = Modifier.nestedScroll(scrollBehavior.nestedScrollConnection),
    bottomBar = {
        AnimatedVisibility(!listState.canScrollBackward || !isCollapsed) {
            BottomAppBar(scrollBehavior = scrollBehavior) {
                //...
                Button(onClick = {
                    scope.launch {
                        listState.animateScrollToItem(0)
                    }
                }) {
                    Text("Scroll to top")
                }
            }
        }
    }
)

isCollapsed and !listState.canScrollBackward is used to determine whether the BottomAppBar should be displayed.

I saw such an implementation on issuetracker. But it not works for me.
