How do you make a LazyColumn reset scroll to zero when a model changes? Code in thread is not working.

// Taken from rememberLazyListState()
val lazyListState = rememberSaveable(searchModel.query, saver = LazyListState.Saver) {
        Log.i(TAG, "New lazyListState")
        LazyListState()
    }
…
LazyColumn(state = lazyListState) {

When the the

query

changes I'd like it to be back at scroll position zero. Instead the column is showing new data, but scrolled into it already.

I would do : LaunchedEffect(query) { lazyListState.scrollTo(0) }

Okay. I used

scrollToItem(0)

since that's all I see. My problem is now it scrolls to zero when I leave and come back to screen, even when

query

doesn't change.
