Question

I copy the code from the default folder to my template, but the field does not appear.
If the field is a regular input, then how to process it programmatically to implement discounts?

If you have such a question, then you should not dig into the cart component. Believe me. The component is not simple. Use the standard one, no customization.
If you still do not believe, then add to the settings"HIDE_COUPON" => "N"
