For Some reason GetChatInterface() is not valid… Here is my code;

bool USteamFriendsFunctionLibrary::CreateSteamChat(APlayerController* Controller, FString RoomName)
{
	IOnlineSubsystem* OnlineSub = IOnlineSubsystem::Get();

	FChatRoomId RoomID = "1";
	FChatRoomConfig RoomConfig;
	RoomConfig.Password = "1234";
	RoomConfig.bPasswordRequired = false;
	RoomConfig.bRejoinOnDisconnect = true;
	if (OnlineSub)
	{
		IOnlineChatPtr ChatInterface = OnlineSub->GetChatInterface();
		if (ChatInterface.IsValid())
		{
			ULocalPlayer* LocalPlayer = Controller->GetWorld()->GetFirstLocalPlayerFromController();
			TSharedPtr<const FUniqueNetId> UniqueNetId = LocalPlayer->GetPreferredUniqueNetId();
			GEngine->AddOnScreenDebugMessage(-1, 15.0f, FColor::Yellow, TEXT("Create Room"));
			return ChatInterface->CreateRoom(*UniqueNetId, RoomID, RoomName, RoomConfig);
		}
		else
		{
			GEngine->AddOnScreenDebugMessage(-1, 15.0f, FColor::Yellow, TEXT("Chat Interface Not Valid"));
			return false;
		}
	}
	return false;
}

as I can see in OnlineSubSystemSteam.cpp it return a null pointer

IOnlineChatPtr FOnlineSubsystemSteam::GetChatInterface() const
{
	return nullptr;
}
