Composable as method parameter

Question

I have a Scaffold composable which is used as the basis of all screens :

    @Composable
fun ScreenScaffold(
    navController: NavController? = null,
    modifier: Modifier = Modifier,
    topBar: @Composable () -> Unit = {},
    hasBottomNavBar : Boolean = false,
    hasGradient : Boolean = true,
    stickyContainerContent: @Composable () -> Unit = {},
    showStickyContainer: Boolean = false,
    surfaceMode: SurfaceMode = SurfaceMode.OnBackground,
    stickyContainerSurfaceMode: SurfaceMode = surfaceMode,
    onBackButtonPressed: (() -> Boolean)? = null ,
    content: @Composable () -> Unit) {

And TopBar parameter is a composable like this:

@Composable
fun TopBar(
    title: String? = null,
    titleAlign: TextAlign = TextAlign.Start,
    hasLargeTitle: Boolean = false,
    largeTitleTextStyle: TopBarLargeTitleTextStyle = TopBarLargeTitleTextStyle.LARGE,
    hasBackButton: Boolean = false,
    backButtonTint: Long = OneAppTheme.colors.topNavIconColor,
    backButtonOnClick: () -> Unit = {},
    rightButtonImageToken: String? = null,
    rightButtonTint: Long = OneAppTheme.colors.topNavIconColor,
    rightButtonOnClick: () -> Unit = {},
    surfaceMode: SurfaceMode = SurfaceMode.OnBackground,
    scrollBehavior: TopBarScrollBehavior? = null,
) {

Right now if I wanna pass a callback for back button handling, I have to pass it twice for both ScreenScaffold and TopBar (onBackButtonPressed and backButtonOnClick respectively). How can I pass that callback just once to ScreenScaffold and then somehow pass it to TopBar?

Thanks.
