can a Stripe checkout session be initiated for anonymous user?

[desert-dionysus]

My goal is to create a Stripe checkout session for an anonymous user to subscribe, then use the customer information collected during checkout to build a User in Rails via the return_url, but everything I've looked at seems to imply that I must use current_user.payment_processor.checkout to instantiate the session with Pay gem -- I suppose I can just fall back to the classic Stripe API but curious if there's a proper way to do this with the gem?

Thanks!
