How to add total order amount for payment.php template?

Question

WordPress

You need to add the product name (for the form-checkout.php template). The total amount of the order (for the payment.php template).

I tried to take the existing code from other templates, which is responsible for the product name, the total cost from review-order.php, order-details.php. The withdrawal method did not work.

upd. It seems that I figured out the total amount of the order for payment.php. The working method was taken out of review-order.php It <?php wc_cart_totals_order_total_html(); ?>

remains to decide with the name of the product for form-checkout.php
