[Feature] Pass PaymentIntent to ExternalPaymentMethodConfirmHandler

[azazellj]

Is your feature request related to a problem? Please describe.

When payment is initialized, PaymentIntent is not passed to the callback, I must do API call to retrieve needed data.

Describe the solution you'd like

fun confirmExternalPaymentMethod(
        externalPaymentMethodType: String,
        billingDetails: PaymentMethod.BillingDetails,
        paymentIntent: PaymentIntent?,
)

Describe alternatives you've considered

Additional context

I'm doing an external payment and I must pass amount & currency into it.

Hi @azazellj - you can solve this without adding it on the Stripe side by passing this data to your callback, or storing it in a centralized place that it has access to.

We can't pass the PaymentIntent because not all integrations use Payment Intents, and some integrations don't provide us the Payment Intent in this flow.
