It does not work like that.

You have to setup how to get paid, and cancellation policy along with Rate Plan and link rate plan to policy and rooms etc.

This sounds like you have not read all the Partner Help section guides.

Ideally you need to sign up for Payments by Booking to do prepayments indirectly.

Kind Regards
