question

We didn't want our users to directly talk to PlayFab. Instead we wrote CloudScripts to provide the functionality we wanted. To request a multiplayer server, your CloudScript would look something like this:

const BuildId = "[put your build id here]"

// requestGame - requests a game server with the provided sessionId. 
//     If no game server exists then it starts a new one. If a game serve 
//     already exists, then it returns its info. 
// args.sessionId - guid representing the game (ie. could be a 
//     stable-hash of a lobby name).
// returns - buildId, sessionId, serverId, ip, port
handlers.requestGame = function(args, context) {
    var request = {
        "BuildId": BuildId,
        "SessionId": args.sessionId,
        "SessionCookie": "",
        "InitialPlayers": [
        ],
        "PreferredRegions": [
            "EastUs"
        ]
    };
    var result = multiplayer.RequestMultiplayerServer(request);
    return {
	"buildId": buildId, 
	"sessionId": sessionId, 
	"serverId": result.ServerId, 
	"ip": result.IPV4Address, 
	"port": result.Ports[0].Num
    }
}

how can i use the cloudscrid. do i need any command?
