I'm trying to center an ImageView within a ConstraintLayout as seen below.

```
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    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="match_parent">

    <ImageView
        android:src="@android:drawable/presence_busy"
        android:layout_width="70dp"
        android:layout_height="70dp"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

```

This is the result:

I'm currently using `androidx.constraintlayout:constraintlayout:2.0.4`.

How do I center the ImageView?
