Is SEPA with a sourceId created from a payment instrument supported?

[Eusebiotrigo]

I have seen that in the documentation there are 2 ways of integrating with SEPA, with and without a source.

I have seen that there are 2 objects,

SepaSource, under com.checkout.handlepaymentsandpayouts.payments.common.source.sepasource
and
RequestSepaSource under com.checkout.payments.request.source.apm

I have also seen that in the tests there is some reference to SEPAv4, but it creates a request without a Source.

Is the integration with a Source supported by the SDK?

Unless, it is this one the one we should use RequestIdSource
