How stop BottomSheet from Overlaying BottomNavBar (with Jetpack Compose)

Question

This is my first time using the BottomSheet.

I follow a tutorial and implemented the bottomsheet in a code with bottomnavbar. This was the result. {The bottomsheet overlaps the bottomnavbar, when it is collapsed}

As you can see the bottomsheet overlays the bottomnavbar.

Here's the code of the bottomSheet

@SuppressLint("UnusedMaterialScaffoldPaddingParameter")
@OptIn(ExperimentalMaterialApi::class)
@Composable
fun BottomSheetLayout() {


    val bottomSheetItems = listOf(
        BottomSheetItem(title = "Notification", icon = Icons.Default.Notifications),
        ...
    )

    val bottomSheetScaffoldState = rememberBottomSheetScaffoldState(
        bottomSheetState = BottomSheetState(BottomSheetValue.Collapsed)
    )
    val coroutineScope = rememberCoroutineScope()
    BottomSheetScaffold(
        scaffoldState = bottomSheetScaffoldState,
        sheetShape = RoundedCornerShape(topEnd = 30.dp),
        sheetContent = {
            Column(
                content = {
                    Spacer(modifier = Modifier.padding(16.dp))
                    Text(
                        text = "Create New",
                        modifier = Modifier
                            .fillMaxWidth(),
                        textAlign = TextAlign.Center,
                        fontWeight = FontWeight.Bold,
                        fontSize = 21.sp,
                        color = Color.White
                    )
            LazyVerticalGrid(
                //cells = GridCells.Fixed(3),
                columns = GridCells.Fixed(3)
            ) {
                items(bottomSheetItems.size, itemContent = {
                    Column(
                        horizontalAlignment = Alignment.CenterHorizontally,
                        modifier = Modifier
                            .fillMaxWidth()
                            .padding(top = 24.dp)
                            .clickable {

                            },
                    ) {
                        Spacer(modifier = Modifier.padding(8.dp))
                        Icon(
                            bottomSheetItems[it].icon,
                            bottomSheetItems[it].title,
                            tint = Color.White
                        )
                        Spacer(modifier = Modifier.padding(8.dp))
                        Text(text = bottomSheetItems[it].title, color = Color.White)
                    }
                })
            }
                }, modifier = Modifier
                    .fillMaxWidth()
                    .height(350.dp)
                    //.background(MaterialTheme.colors.primary)
                    .background(
                        brush = Brush.linearGradient(colors = listOf(MaterialTheme.colors.primary, Color.White)
                        )
                    )
                    .padding(16.dp)
            )
        },
    ) {
        Column(modifier = Modifier.fillMaxSize()) {
            Button(
                modifier = Modifier
                    .padding(20.dp),
                onClick = {
                    coroutineScope.launch {
                        if (bottomSheetScaffoldState.bottomSheetState.isCollapsed) {
                            bottomSheetScaffoldState.bottomSheetState.expand()
                        } else {
                            bottomSheetScaffoldState.bottomSheetState.collapse()
                        }
                    }
                }
            ) {
                Text(
                    text = "Click to show Bottom Sheet"
                )
            }
        }
    }
}

Thanks for your help in advance.

I'd also appreciate any tip and advice about the bottomSheet, thanks again.
