Just be aware that, no matter how seamless it is, you still getting crazy bounce rates for it. You would need a really good reason to use it (basically, be a bank and need KYC or something).
Of course, a common use case for this would be to only show the Stripe Identity UI when a user has a higher chance (based on IP, time of day, other on-site behavior, etc.) of being fraudulent in the first place, in which case a higher bounce rate is a feature, not a bug.
