FPWCSApi2RoomManager vs FPWCSApi2Session & VoD

Hello, at the moment I have seen two basic ways of establishing a connection to the server using either FPWCSApi2RoomManager or FPWCSApi2Session. Each method offers different functionality on how to play a live stream. How about VoD? Can FPWCSApi2RoomManager play a VoD file? If not, can I publish/restream a file on the server and then play it as a live/participant stream using FPWCSApi2RoomParticipant.play?
Thanks for reply. My bad, I missed that FPWCSApi2RoomManager class contains a reference to FPWCSApi2Session that has an option of playing a VoD file along with live streams from participants.
