I'm using PayPal and want to add the payment method SEPA on my current website. Here are some examples I have followed:

1. https://developer.paypal.com/docs/checkout/integration-features/standalone-buttons/#funding-sources
2. https://demo.paypal.com/de/demo/go_platform/pcRestServerV2/paymentOptions

So basically I'm not getting SEPA button as displayed here on above 2nd link.
