I have the following lines of code in my website that will display the ***related products*** at the bottom of my single product page in WooCommerce...

**functions.php:**

    // display upsells and related products within dedicated div with different column and number of products
    remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_related_products',20);
    remove_action( 'woocommerce_after_single_product', 'woocommerce_output_related_products',10);
    add_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_related_products', 20);
    
    function woocommerce_output_related_products() {
    	$output = null;
    
    	ob_start();
    	woocommerce_related_products(4,4); 
    	$content = ob_get_clean();
    	if($content) { $output .= $content; }
    
    	echo '<div class="clear"></div>' . $output;
    }

As it displays 4 products that have been categorized under the same name, how would I modify the above, to display the ***related tags*** instead?
