Hello!

I’m using UE 5.5.4 and [Advanced Sessions](https://vreue4.com/advanced-sessions-binaries) Plugin, add lines to _DefaultEngine.ini_

```auto
[/Script/Engine.GameEngine]
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[OnlineSubsystem]
DefaultPlatformService=Steam  

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"

```

And then I add game to Steam as Non-Steam Game

But not in Standalone mode not in the development build does not open the overlay of Steem.

If anyone knows the solution to this problem I would be immensely grateful
