Hide used discount code from "Order Successful Page"

We have a custom checkout system allowing users to upgrade from a previous verison of a software to the current version. This is using discount codes that get applied on checkout via the checkout overlay. We use php to process them in order for the users to NOT see the discount codes (since they would be shareable). Unfortunately the system has one fatal flaw:

• The “order successful page” that lemon squeezy shows after an order is completed actually shows the used discount code. You also can see it whenever you access your past orders.

This is quite bad as it invalidates the “hidden discount” system and requres us to always generate discounts on demand which adds code and maintenance - instead of just having one easily managable discount code directly on the Lemon Squeezy Dashboard.

Please remove or add the option to remove the display of Discount Codes from the “Order Successful” Page
