Hello, I am trying to integrate PayPal's advanced checkout. But I haven't found a way to truly customize the card fields. I am using JS SDK and the input fields are rendered through an iframe. I can change the padding inside the card input field as per the documentation, but cannot change anything related to the border since there is no mention of it. I would prefer to change the border size as well as the border color to match my site design. It would be helpful to know any input on how this can be implemented.
