I developed an app with a payment extension and now I need to configure the provider. I am the provider myself, and I am trying to activate it in my development store. How do I solve this? I am developing a payment application on Shopify with the aim of adding a new external payment method to the checkout. So far, I have: I created the app with a payment extension that can be installed + A Laravel app bridge that would be the back office. However, after installing and having the back office functional, when adding the payment method I get the message: 'Not accepting payments with Offsite Payments App Extension. Complete your account setup with this provider to start accepting payments.
