How to call Steamworks API from c++ classes

Development Programming & Scripting

I’ve just started with UE5 and there’s a lot of examples how to create a session via Steam, but there’s no any examples how to call Steamworks api. I want a basic, get a player name. I set up steam online subsystem, but API is still unavailable. Here’s my GameInstance class.

#include "MyGameInstance.h"

UMyGameInstance::UMyGameInstance() {

}

void UMyGameInstance::Init() {
    Super::Init();
    // SteamAPI_Init(); should I use it?
    IOnlineSubsystem* Subsystem = IOnlineSubsystem::Get();
    const FOnlineSubsystemSteam* Oss = static_cast<FOnlineSubsystemSteam*>(Subsystem);
    // this line gives me "Cannot resolve symbol 'SteamUser'"
    const auto SteamID = FString(std::to_string(SteamUser()->GetSteamID().ConvertToUint64()).c_str());   
    
    const auto AppID = FString(std::to_string(Oss->GetSteamAppId()).c_str());
    GEngine->AddOnScreenDebugMessage(-1, 15.0f, FColor::Yellow, AppID);
}

But SteamUser or SteamAPI_Init are unavailable. Also I found in the class UE_5.0\Engine\Plugins\Online\OnlineSubsystemSteam\Source\Private\OnlineFriendsInterfaceSteam.h GetRealName() and GetDisplayName() functions, can I somehow use it?

#include “steam/steam_api.h” made the trick. Can be closed now.
