Access User's Data - Mongo Realm Kotlin SDK

I’m using JWT provider for the authentication. Also from that JWT I’m getting some custom fields like: name, email, picture and I’m successfully saving them on my Mongo DB Atlas. I can see those information about the user when I open up: App Services > App Users.

But my question is, how can I access those information from my own app? When I try to get the current user for example I use something like: "App.create(APP_ID).currentUser"

But from that user I cannot access any data, except the ownerId/identity. Any solution?

Can someone point me in the right direction on this?
