I really apreciate your answer. But  don't know how to solve this:

Before configuring the FACe system, install the Spain - Facturae EDI (l10n_es_edi_facturae) module.

I don't know where to find the module.​

In Odoo 17 you can look at the documentation, I have not been able to attach the link right now, but look in "Documentation/Tax locations/Spain", there it talks about tax models, FACE and Sii
