Adding the ‘sytles’ attribute worked for me. On the front-end if you want the style classes to show up on the HTML, you can use the $block['className'] global variable.

$className = 'acf-card';
if( !empty($block['className']) ) {
    $className .= ' ' . $block['className'];
}

I found this in the blocks documentation under “3. Render the Block”
