I have implemented Shopify APIs suscessfully in android app. While checkout I got a checkout ID but after this when I use Payment with credit card I get this error "Credit Card checkout: CheckoutCompleteWithCreditCard access denied". Moreover on github there is a note below Credit Card Payment saying
Before completing the checkout with a credit card, you need to have the write_checkouts_payments scope enabled for your app
Its a permission issue but i can't figure out how to enable it.
