Accessing Player's Oculus Username and Displaying it in-game.

Hello,

I'm developing a multiplayer VR game for Quest and Windows PCVR. Unity 2023.2.19, XR Plug-in is set to OpenXR, latest XR plugins, and Meta XR Platform SDK 68.0.0.

I've only pieced together loose information online to make this system for grabbing and displaying the player's Oculus/Meta/Account username, but I need help because it's not working. I'm going this route because I don't want to add moderation and check for unique usernames if Meta already has these systems. 

I made sure that the Meta XR Platform SDK was in my project which is the only Meta package I have: Meta XR Platform SDK | Integration | Unity Asset Store

It builds and runs fine, it authenticates successfully thanks to the instructions from here: https://developer.oculus.com/documentation/unity/ps-entitlement-check/

try
{
    Core.AsyncInitialize(appID); //Their docs had "Platform.Core.AsyncInitialize(appID), but their example only had ()"
    Entitlements.IsUserEntitledToApplication().OnComplete(EntitlementCallback);
}
catch(UnityException e)
{
    Debug.LogError("Platform failed to initialize due to exception.");
    Debug.LogException(e);
    // Immediately quit the application.
    UnityEngine.Application.Quit();
}

// Called when the Meta Horizon platform completes the async entitlement check request and a result is available.
void EntitlementCallback (Message msg)
{
    if (msg.IsError) // User failed entitlement check
    {
        // Implements a default behavior for an entitlement check failure -- log the failure and exit the app.
        Debug.LogError("You are NOT entitled to use this app.");
        UnityEngine.Application.Quit();
    }
    else // User passed entitlement check
    {
        // Log the succeeded entitlement check for debugging.
        Debug.Log("You are entitled to use this app.");
        
        // From https://communityforums.atmeta.com/t5/Unity-VR-Development/How-do-i-access-oculus-username/td-p/889007
        Oculus.Platform.Users.GetLoggedInUser().OnComplete(GetLoggedInUserCallback);
    }
}

private void GetLoggedInUserCallback(Message msg) {
    if (!msg.IsError) {
        User user = msg.GetUser();
        Oculus_userName = user.OculusID;
        Oculus_displayName = user.DisplayName;

        PlayerUsernameWeWillSet = Oculus_displayName;
    }
    else
    {
        setDefaultPlayerNameInstead = true;
    }
}

But when I try to use PlayerUsernameWeWillSet, it's not null or empty because I have checks to set it to a generic player name instead. I know it can take a few seconds, so I have logic to rerun a coroutine every so often trying to see if we got the username but it's still not getting it. My PCVR version is working with a username I'm grabbing from a different source, it displays properly in a text field.

Maybe you see the problem, but if you don't you can help me know how to debug this and get a log after building it as an APK which I haven't tried yet.

Thank you.
