UE5 PlayFabSDK+SubsystemPlayFab Lobby/Party Invites

Hello, I'm trying to make a system that will provide the following process for players:

1) Player1 sends a party/lobby invitation.

2) Player2 accepts the invitation.

3) Players get a shared text chat and voice chat.

4) Player1 initiates matchmaking.

5) Player2 receives matchmaking start notification.

6) Players connect to the game.

I decided to go with the lobby but discovered that the PlayFabSDK plugin does not have callbacks.

The documentation says that you need to use SubsystemPlayFab for the lobby and party. However, after generating the engine project, the Platforms folder does not appear with the files necessary for the lobby code, such as "Party.h" and "PFLobby.h"

Is it possible to make callbacks using PlayFabSDK only? If not, what can I do to make the Platforms folder visible in Visual Studio so I can use "Party.h"?

The documentation contains examples of code for invites, but it does not indicate which headers are needed for this. lobby-invites If I'm moving in the wrong direction, please tell me what to do.

Best regards.

If you want to have text chat and voice chat feature in Unreal Engine, PlayFab SDK alone may not be sufficient for your needs , you have to use the PlayFab OnlineSubsystem (OSS).

Have you follow the PlayFab Online Subsystem (OSS) Quickstart - PlayFab | Microsoft Learn to setting up? After you finish the initial setting up, then you may follow the PlayFab Online Subsystem (OSS) Quickstart - PlayFab | Microsoft Learn to use the PlayFab OSS. In addition, since PlayFab OSS layer works seamlessly on top of the existing base platform OSS layers (such as the base GDK OSS layer provided by Epic for Xbox and PC Game Pass). It's designed to be used behind the IOnlineSession interface provided by Epic, you may also refer to Online Subsystem Session Interface in Unreal Engine | Unreal Engine 5.0 Documentation to learn how to use OSS.

From what I can see, the Session Interface only has one call OnSessionInviteReceived. Is it ok to receive a lobby invite? How can I join lobby if this call does not return a connection string?

Since PlayFab OSS has encapsulated Lobby, Matchmaking and Party function according to the UE OSS interface, it cannot be used like the Client SDK. After getting the IOnlineSessionPtr with GetSessionInterface method, you will need to refer to Epic's documentation Online Subsystem Session Interface in Unreal Engine | Unreal Engine 5.0 Documentation and IOnlineSession | Unreal Engine Documentation to learn how to use OSS. With OSS, you should be able to join lobbies with IOnlineSession::JoinSession().
