Close button touchable area is (too) small

[curiousily]

Hey,

Currently, the close button is defined as

 <ImageView
        android:id="@+id/imageViewShowCaseClose"
        android:layout_width="36dp"
        android:layout_height="36dp"
        android:padding="11dp"
        android:scaleType="centerCrop"
        android:src="@drawable/ic_close"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

This is way to small. According to this: https://support.google.com/accessibility/android/answer/7101858?hl=en the touchable area should be at least 48x48 dp

Thanks for making this amazing library!
