I noticed that there is a "Pay with Amazon" button in the side cart when I set up the "Amazon FPS" option as a valid payment type in the admin section. Since "Amazon FPS" is deprecated, I am using the new "Amazon Payments" payment option instead, but I don't see a similar button for that payment type.
Is it possible to have a similar button for Amazon Payments... maybe a "Pay with Amazon" or "Checkout with Amazon" button on the side cart, so that the user can login with Amazon first before seeing the checkout page?
Thank you!
