How can a PC user get their Nitro + EA Access codes after subscribing to Ultimate?

I don't have the xbox one console yet, and I haven't found any way to get my promo codes for Nitro, EA Access and Spotify.

I'm from Brazil, so the offer is certainly valid around here. I've been waiting for any notification from the Game Pass Android App, or the Game Pass for Windows, or maybe an email, but haven't got any of those.

The only answers I got so far mention getting the codes from the XOne dashboard, and that's the one thing I can't do right now.

Also I haven't found any means to contact support directly, so I don't even know if Microsoft knows there are a lot of PC users waiting for their codes.
