I would like to specify some of the parameters that are available to the GetToken request in Xsolla (wrapped by PlayFab's GetPaymentToken). In particular I'd like to set the paystation UI to the dark theme.

If I was able to pass along data to the token request, I could specify this and other settings that I'd be interested in. Is this possible somehow?
