In Galicia we have the app and you can easily download the passport.In Spain there is no app as such, since the health competencies are held by the autonomous communities, and each of them has its own app. None of them offer support to add it to the wallet or the health app. In fact, I have been able to add it to the Wallet with the steps I described before, but not in the health app, I don't have a way to put it there.
