In compose lazy column, why there is no default option to show scrollbar?

Question

In compose ui, lazy column or row, there is no default option to show scrollbar like in xml(android:scrollbars="vertical").

<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:scrollbars="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
