Discount for a group product, how to add?

Question

WordPress

How to add a single price to a group product in woocommerce and put a discount?
The bottom line is that there is a product card, and a block of a set of this product with another product is displayed on it, and you need to make them together cheaper than when buying separately. Those. the price of a set (group product) must be the same, not a range (from and to), and with the ability to add a discount that will be applied to the order only when purchasing the entire set.
Is it possible to implement this, if so, in which direction to dig?
