Steam player nickname from Steam ID not working

Good afternoon everyone,
I am trying to set up an online leaderboard using the Epic Leaderboard plugin and the Advance Online session plugin for steam.
I am submitting as username the Steam ID but I want to display the player nickname in the UI

The problem is that the player nickname always print only my Steam Nickname… even if printing only the steam ID as string result in having different steam ID.
So my question is why the player get NIckname only gives me my player nickname? no matter what is the actual steam ID

I think you need to call RequestSteamFriendInfo and wait for the result first.
