Button is displayed even when Out Of Stock

Hello,

I’m using your “WooCommerce Amazon Pay” plugin for my WooCommerce store with a Divi theme, everything is up-to-date and looks fine. The only issue I’m having with your plugin is that it does display Amazon Pay button on a product page despite on its stock. Customers can see the Amazon Pay button even for the products which are out of stock. The Add to cart button (created by a Divi module) works well (it is not displayed if a product is out of stock), but your plugin button does it any way.

This is how it looks like (no Add to cart button, just Amazon Pay one): https://www.dropbox.com/s/7ypu2qpayfsroda/Screenshot%202023-02-17%20at%2015.14.15.png?dl=0

Please fix the issue so that Amazon Pay button is not displayed if the product is out of stock.

Also, it’s not very handy that Amazon Pay sticks under the first Add to cart button on the page (even if it’s hidden). It would be much better if it sticks under not the first one, but under the visible one.
