[Resolved] wp_dequeue_style( 'wp-block-library' ) doesn't seem to work in Elements

I’m trying to stop the block library css from loading. I created an Element with this as the content:

<?php

add_action( 'wp_enqueue_scripts', 'remove_wp_block_library_css' );

function remove_wp_block_library_css(){
wp_dequeue_style( 'wp-block-library' );
wp_dequeue_style( 'wp-block-library-theme' );

}
?>

However it’s still loading: https://www.terrys-service.com/wp-includes/css/dist/block-library
/style.min.css?ver=5.4.1

I tried the element in both wp_head and wp_footer with the “execute php” checkbox checked, but the file still gets loaded.

Any suggestions?

Thanks!

Terry
