Autofill for Stripe V3 Element (iframe)

Looking for a script or small application to autofill Stripe V3 Elements with all payment information. Solution must load on iframe load (or before), and must successfully obtain payment token upon hitting submit. No other input must be required - must account for postal code when prompted. I am asking that the solution will AUTO COMPLETE THE FIELDS REQUIRED FOR PAYMENT - this should allow for sub 1 second checkouts. To be clear, I want to use this tool on multiple stripe-enabled websites so that I can complete checkout within < 1 second. Every field should be completed: cardNumber, cardExpiry, cardCvc, postalCode. Here are some example sites where it should autofill on page load: [login to view URL] [login to view URL] [login to view URL] Solution should be simple, clean, user friendly and should work on at least chrome, via script or small app. Thanks!
