How to Set Up Meta Pay for In-App Purchases in the Store

I’m currently figuring out how to integrate Meta Pay into our game’s in-app purchase (IAP) system within the Store from the Developer Dashboard.

I’ve reviewed the docs here: https://developers.meta.com/horizon/resources/add-ons-setup#creating-add-ons-and-adding-store-assets and the YouTube tutorial here: https://www.youtube.com/watch?v=Fefo_s8BUS4&t=5s, but I’d like to confirm the correct process for configuring Meta Pay.

My main questions are:

1. How do you connect Meta Pay to an IAP setup in the Store?
2. What steps are required to enable payment settings, including linking Meta Pay (e.g., binding credit cards or bank accounts)?
3. Is there an official tutorial or guide that explains the full setup process?

Any guidance or resources would be greatly appreciated!
