How to use

for column :

Column(Modifier
    .fillMaxSize()
    .overScrollVertical() // invoke before the scrollable Modifier
    //.overScrollHorizontal() // or this
    .verticalScroll(state = scrollState, flingBehavior = rememberOverscrollFlingBehavior { scrollState }) // must use rememberOverscrollFlingBehavior
    //.horizontalScroll(state = scrollState, flingBehavior = rememberOverscrollFlingBehavior { scrollState }) // must use rememberOverscrollFlingBehavior
) {
    // ...
}

for scrollable Composable like lazyColumn :

  val scrollState = rememberLazyListState()
        
        LazyColumn(Modifier
            .fillMaxWidth()
            .overScrollVertical(), // * u should do it
            state = scrollState, // * u should do it 
            flingBehavior = rememberOverscrollFlingBehavior { scrollState } // * u should do it after compose 1.3.x because this's a added param.
        ) {
            // ...
        }

U can call it nested! pls see the demo!
