...
"References": [
    {
        "Name": "$(EnginePath)/Flax.flaxproj"
    },
    {
        "Name": "$(ProjectPath)/Plugins/OnlinePlatformSteam/OnlinePlatformSteam.flaxproj"
    }
]

3. Add reference to Steam plugin module in you game code module by modyfying Source/Game/Game.Build.cs as follows (or any other game modules using Online):

/// <inheritdoc />
public override void Setup(BuildOptions options)
{
    base.Setup(options);

    ...

    switch (options.Platform.Target)
    {
    case TargetPlatform.Windows:
    case TargetPlatform.Linux:
    case TargetPlatform.Mac:
        options.PublicDependencies.Add("OnlinePlatformSteam");
        break;
    }
}

This will add reference to OnlinePlatformSteam module on Windows/Linux/Mac platforms that are supported by Steam.

Finally you can use Steam as online platform in your game:

// C#
using FlaxEngine.Online;
using FlaxEngine.Online.Steam;

var platform = new OnlinePlatformSteam();
Online.Initialize(platform);

// C++
#include "Engine/Online/Online.h"
#include "OnlinePlatformSteam/OnlinePlatformSteam.h"
