No static method AnimatedContent - Jetpack Compose

I'm trying to animate adding/removing items from a LazyList. This post suggests that I use LazyItemScope$Modifier.animateItemPlacement() but I am running into issues.

I am using Jetpack Compose version 1.1.0-beta03. Here is a snippet of the code I'm using:

@ExperimentalFoundationApi
@ExperimentalAnimationApi
@ExperimentalMaterialApi
@Composable
fun NotificationList(
    listState: LazyListState,
    notifications: List<Notification>
) {
    Surface(modifier = Modifier.fillMaxSize()) {
        LazyColumn(state = listState) {
            itemsIndexed(
                items = notifications,
                key = { _, listItem -> listItem.hashCode() }
            ) { _, notification ->

                // ...

                SwipeToDismiss(
                    modifier = Modifier.animateItemPlacement(),
                    // ...
                )
            }
        }
    }
}

However, my app crashes when launched. Below is what I see in the console. Does anyone know what I'm doing wrong or how to fix it?
