For application while not in Argentina, I've never needed anything to be officially translated or apostatized.
It runs through the embassy local to your region and they can work bi-lingual.
Just for convenience though, everything self-made like the resume I sent in with one page English and one page Spanish just for max user friendliness across me, embassy, and headquarters. Nothing official though.
P.S. I don't think you can even get any of the nomad items apostatized.
Apostle is only for government issued items like birth certs. or FBI background checks. Nomad visas just want a resume and proof of job/income really.
