1/ yes it's normal
2/ https://stripe.com/docs/payments/accept-a-payment?platform=web&ui=elements#web-submit-payment that's what we do here in the second bit of code to display/show success

But really if it were me I wouldn't use those. I'd have a cookie/session to know who my customer is, what PaymentIntent they are completing and rely on that
