Android back arrow has no visual feedback on click

When I click on the back arrow, it works fine. But Google Apps have a visual effect showing a rounded dark circle. How can I add this?

<androidx.appcompat.widget.Toolbar    android:id="@id/toolbar"    style="?attr/toolBarStyle"    android:layout_width="match_parent"    android:layout_height="?attr/actionBarSize"    android:contentInsetEnd="0dp"    android:contentInsetLeft="0dp"    android:contentInsetRight="0dp"    android:contentInsetStart="0dp"    app:contentInsetEnd="0dp"    app:contentInsetLeft="0dp"    app:contentInsetRight="0dp"    app:contentInsetStart="0dp"    android:theme="?attr/actionBarTheme"    tools:targetApi="lollipop">

icn_navigation_back.xml

<vector xmlns:android="http://schemas.android.com/apk/res/android"        android:width="48dp"        android:height="48dp"        android:viewportWidth="48.0"        android:viewportHeight="48.0"><path        android:pathData="M19.8,23l5.59,-5.59l-1.41,-1.41l-8,8l8,8l1.41,-1.41l-5.59,-5.59l12.17,0l0,-2z"        android:strokeColor="#00000000"        android:fillColor="#003B5A"        android:strokeWidth="1"/></vector>

The icn_navigation_back is loaded into an ImageView:

<ImageView            android:id="@+id/toolbar_navigation_button"            android:layout_width="56dp"            android:layout_height="match_parent"            android:scaleType="centerInside" />
