Help displaying players on place on main menu

Does anyone has an idea on how you would get the player count of a place? I have seen in DevForum where they use a HTTP request to get the data from roblox API, but this gets the game total player count, lets say we have a game with three places, a main menu and two maps, how can I show the total amount of players playing on each map on the main menu place?

You can use messaging service to send the amount of players in it simply with #game:GetPlayers()
