You don't need to manage SetupIntent, it's not necessary to explictly cancel a SetupIntent.

https://stripe.com/docs/payments/accept-a-payment-deferred?platform=web&type=setup there's also another flow that allows you to display PaymentElement without creating a SetupIntent first.

Build an integration where you can render the Payment Element prior to creating a PaymentIntent or SetupIntent.
