The Apple Pay button is not showing in the PayPal integration

I tested this code locally using the same .env with Ngrok and my server (rehosting localhost:3000 like Ngrok), and the button appears on both Mac and iPhone. However, when I deploy it on Netlify with a domain and HTTPS, the button doesn't appear. I've added the Apple well-known file to the backend, and I've also registered the domain with PayPal for Apple Pay.
