What loyalty module do you recommend for PrestaShop?

Question

Prestashop

Hello! I am looking for a suitable loyalty program module for Prestashop. I don’t like the standard one for its complexity bonuses = a percentage of the price of the goods, bonuses are converted into coupons, coupons can be used to pay for a purchase. Why these coupons - I do not understand.
Ideally, for the purchase of goods, a percentage of the cost of the goods is charged to the internal balance, which can be paid in the basket. All.
Or am I missing something and the bonus-coupon scheme is somehow very cool and convenient?
