I can't use Users API functions

Hi! I'm using Outsystems version, and I have problems using the Users API functions.

I'd tried to follow the next post: https://www.outsystems.com/forums/discussion/36266/mobile-app-how-do-i-simply-display-current-users-name-or-username/ but I can't use the function "User_GetName()"

Hope this can help.
