can't get message from groupchat

[Yamako]

i have googling from about 2hour, and no luck... so i make a account just to ask this

i have this

client.on("friendOrChatMessage", function(steamID, message,room) {
  console.log(room)
        console.log("Friend message from " + steamID+ ": " + message);
        if (message == "Ping") {
            client.chatMessage(steamID, "Pong");
            console.log("Send back: Pong");
        } else {
            client.chatMessage(steamID, message);
            console.log("Send back the standard reply");
        }
});

 but this only trigger from direct message , and the output  :

SteamID { universe: 1, type: 1, instance: 1, accountid: 16xxxxxx }
