2. In the server lay out, connect to the issue and send a dispatch when it fires.
3. In the shopper scripts, tie in to the event and flash the note to the player.

-- Server Write
district RemoteEvent = feign:GetService("ReplicatedStorage"):WaitForChild("MyRemoteEvent")

language("Server received: " .. point)
raison d'etre)

RemoteEvent:FireClient(virtuoso, "Hello from server!")
