Is your feature request related to a problem? Please describe.
I have pored over the documentation, and I can't see a clear-cut way to override the theme of the payment sheet. For instance - I have an app that has light and dark screens. The PaymentSheet always defaults to the system theme over the app theme. Google is rejecting the app becauase it's showing light buttons on a light background when I update the bg, but I can't find a way to choose light/dark versions of the elements components when presenting a paymentSheet.

Describe the solution you'd like
A setting or object in Appearance that would allow you to override the theme mode 'light/dark' that you can drill into with component/element-specific styling as well.

Describe alternatives you've considered
The only alternative I see is using Elements, but that seems foolish just to set one setting.
