Issue with adding credit/debit card payment method

Hi! I’m working with T-Shirt Market template (online store template) to set up a pizza delivery website for a Malaysian company. Before upgrading to a premium plan, I started connecting payment methods to the website but I found out that I can only add PayPal and Cash On Delivery. I really need to add credit/debit card payments so I was wondering how I can solve this issue. Are the limited payment options related to the template or the geographic area? Is it possible to unlock other payment options?

Thanks in advance for the help.
