AssetService question, can someone help?

I am creating a game which has a lobby server and then a map that the user can teleport to when they have created their character etc... I was wondering if it was possible to list all the available server and amount of players (like in 'The Plaza'). Here is my code so far:

local TP = game.Workspace.TeleportPlayer
newPlace = game:GetService("AssetService"):CreatePlaceAsync("City", 348764007)

function TP.OnServerInvoke(player)
    print(player.Name)
    game:GetService("TeleportService"):Teleport(newPlace, player)
    return "Complete"
end

I tried using this because it sounds like what I'm trying to do but I have never used pages before so don't know what to do.
