Stripe presentWithSetupIntent does not show the PaymentSheet for SetupIntents

I've tested the Stripe's PaymentSheet for PaymentIntents, passing the payment intent client secret, the customer id and the ephemeral key. I succeeded on closing a payment, both with and without the bank verification step.

I'm trying to use the SetupIntent because I need to authorize now a payment but to bill users in the future. So I've generated a scheduled subscription for a customer and obtained a setup intent client secret.

My problem is, when I call

paymentSheet.presentWithSetupIntent(
    setupIntentClientSecret,
    PaymentSheet.Configuration(
        merchantDisplayName = Constants.MERCHANT,
        customer = PaymentSheet.CustomerConfiguration(
            customerId,
            ephemeralKeySecret
        )
    )
)

I see the payment sheet coming out from the bottom with only an infinite progress bar, as if the setup intent was invalid.
