Automatically generated coupon sent via email

Hello,
I would need 5 100% discount codes to register for a learnpress course to be sent to the buyer when purchasing a woocommerce product.
Is it possible?
How can I automatically generate coupon codes and insert them in the purchase confirmation email?
Learnpress relies on woocommerce for purchases and billing. So can I be sure that the coupon codes generated by wordpress will be valid for Learnpress?
Do I need any add-on?
Thanks
