Steam Overlay doesnt work, help please

Hi there, for some reason SteamOverlay won’t work, I copied this code

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

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480

; If using Sessions
; bInitServerOnClient=true

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

Placed my own AppID, Steam is open, I’m logged in, playing in standalone mode, manually add SteamSDK in source folder, changed AppID in the document steam_appid.txt, I also copied that document to the folder where my game exe is.

What am I doing wrong ?
Does the game needs to be published for the overlay to work ? BTW, overlay didnt work on AppID 480

Can someone help please ?

Ok so i figured out the problem, for those who will encounter the same problem, you need to create standard package in steamworks, only then your app id and name will show xD
