How to add Stripe with multiple Checkout options?

I am having a hard time setting up my Checkout. i tried paypal but the checkout with SEPA and Credit/Debit Card doesnt work somehow - i dont know why! Also, would it be able to delete the SEPA and Credit/Debit Card button somehow?

Now i wanted to switch to Stripe to get the Options to pay via ApplePay, GooglePay, SEPA, Credit Card and so on…
When i connect my Stripe account, the only thing Webflow Checkout allows me to do is just the Credit Card. How can i change that?
Thanks for your help!
