Collapsing toolbar when scrolling through recyclerview

I'd like to achieve collapsing toolbar when scrolling in the RecyclerView items. I've tried many solutions, but the result was not as I'd like to have. What I'd like to get is simply:

When user scroll down, then the toolbar should appear, but when user will scroll up, the it should dissapear.

custom_toolbar

<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="70dp"
    android:background="@color/design_default_color_primary"
    android:fitsSystemWindows="true">

    <com.google.android.material.appbar.AppBarLayout

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true">

        <androidx.appcompat.widget.Toolbar

            android:background="@color/purple_200"
            app:layout_scrollFlags="scroll|enterAlways">

fragment layout
