How can I show my payment app as payment method option in order to test it?

[SeQura]

I'm trying to develop a payment app.

* I have created the shopify app

* I have added the "offsite payment provider" extension type to the app

* I have enabled the "development store preview" option in the app extension

* From the app page I have used the action "Test app on development store" to install it in a development store

* I can see the app installed in the development store's admin

...but I can't see it in as a payment option in the development store's checkout.

Am I missing any step? Where could I look to find any clue of what is wrong?

I think that you are missing onesteps in the flow. At least you didn't mention it.

- Active the payment app in the current store.

Yes, I missed at least that. I can't use permissions stated there: write_payment_gateways or write_payment_sessions, but I found https://community.shopify.com/c/shopify-discussions/oauth-error-missing-shopify-permission-write-pay...

Thank you very much for your help!
