[Solved]How to set discount on google play promo code?

Hello, as the title describes. I am able to create a promo code on Google Play Console, but I can't find how or where to set up a discount for that promotion.

The goal is to create a single use promo code for 50% off of the apps purchase price.

Appreciate any assistance very much!
Thank you

Figured it out. My app is a "paid app" not a subscription. Promo codes for paid apps have only one discount level. Free. Thank you.
