How to use Local Player Arrived From Teleport?

I am trying to fire an event once the player is teleported to the game.

The localscript this code runs in is inside of replicatedfirst (i saw this in other posts so i assumed i put it here)

But for some reason when the player gets teleported to the game, “rejoined!” doesn’t print and there is no output.
Anyone have know why?

local RF = game:GetService("ReplicatedFirst")
local TeleportService = game:GetService("TeleportService")

local win = game.ReplicatedStorage:WaitForChild("Win")


The developer hub explains it and gives a code sample ^
