I am trying to show random product thumbnails from a specific category. I have this code at the moment but it is not working and will show from all products, how to randomize from a specific product category?

    <?php
        $args = array(
        'posts_per_page'   => 1,
        'orderby'          => 'rand',
        'post_type'        => 'product' ); 
    
         $random_products = get_posts( $args );
    
         foreach ( $random_products as $post ) : setup_postdata( $post ); ?>
            <a href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>
         <?php endforeach; 
         wp_reset_postdata();
    ?>
