Custom total savings amount display issue in WooCommerce Checkout

I'm using this code snippet to display the total order savings at WooCommerce checkout:

add_action( 'woocommerce_review_order_after_order_total', 'show_total_discount_cart_checkout', 9999 );
 
function show_total_discount_cart_checkout() {
    
   $discount_total = 0;
    
   foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {         
      $product = $values['data'];
      if ( $product->is_on_sale() ) {
         $regular_price = $product->get_regular_price();
         $sale_price = $product->get_sale_price();
         $discount = ( $regular_price - $sale_price ) * $values['quantity'];
         $discount_total += $discount;
      }
   }
             
    if ( $discount_total > 0 ) {
      echo '<tr class="total-saved"><th>You Saved</th><td data-title="You Saved">' . wc_price( $discount_total + WC()->cart->get_discount_total() ) .'</td></tr>';
    }
  
}

It should display the total amount of money a customer saved (sale prices plus coupon discounts). Screenshot: https://ibb.co/KXg2bDj

However, if there are no discounted products in the cart, the total order savings do not show up, even if there is a coupon code applied to the order. The total order savings show up only if there are discounted products in the cart. Screenshot: https://ibb.co/PCQPGZx

I would like the total order savings to show up if there is a coupon code applied to the order, if there are discounted products in the cart or if there's both. If there's neither 1 of those 2, the total order savings do not need to show up.

Could someone please help me achieve this?

Try the following instead, that will solve your issue and handle displaying tax settings:

add_action( 'woocommerce_review_order_after_order_total', 'show_total_discount_cart_checkout', 1000 );
function show_total_discount_cart_checkout() {
    $discount_total = 0; // Initializing

    // Loop through cart items
    foreach ( WC()->cart->get_cart() as $item ) {
        $product = $item['data'];

        if ( $product->is_on_sale() ) {
            $regular_args = array( 'price' => $product->get_regular_price() );

            if ( WC()->cart->display_prices_including_tax() ) {
                $active_price    = wc_get_price_including_tax( $product );
                $regular_price   = wc_get_price_including_tax( $product, $regular_args );
            } else {
                $active_price    = wc_get_price_excluding_tax( $product );
                $regular_price   = wc_get_price_excluding_tax( $product, $regular_args );
            }
            $discount_total += ( $regular_price - $active_price ) * $item['quantity'];
        }
    }

    if ( WC()->cart->display_prices_including_tax() ) {
        $discount_total += WC()->cart->get_discount_tax();
    }

    $discount_total += WC()->cart->get_discount_total();

    if ( $discount_total > 0 ) {
        $text = __("You Saved", "woocommerce");

        printf( '<tr class="total-saved"><th>%s</th><td data-title="%s">%s</td></tr>', $text, $text, wc_price($discount_total) );
    }
}

Code goes in functions.php file of the active child theme (or active theme). Tested and works.
