Button style is not changing in the AAH_FilterView

[sleepynight2024]

I can change the background and other attributes but setting a whole style is not working for the button and it keeps displaying the default android button style:

<?xml version="1.0" encoding="utf-8"?>
<com.allattentionhere.fabulousfilter.AAH_FilterView

    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <RelativeLayout
        android:background="@color/fancy_btn"
        android:id="@+id/rl_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentBottom="true"
        android:visibility="invisible"
        tools:ignore="MissingPrefix"
        tools:visibility="visible">

        <LinearLayout
            android:background="@color/white"
            android:id="@+id/ll_buttons"
            android:layout_width="match_parent"
            android:layout_height="56dp"
            android:layout_alignParentBottom="true"
            android:orientation="horizontal">
            <androidx.appcompat.widget.AppCompatButton
                android:text="@string/ok_got_it"
                android:id="@+id/btn_close"
                style="@style/ButtonCloseStyle" /> <!-- NOT WORKING -->
        </LinearLayout>

    </RelativeLayout>
