LocalScript does not debounce? What must I change?

Instead of doing a cooldown, it prints "Pressed e" as soon as I press it with no cooldown between presses, then all the "yes"s come in 5 seconds later.

local debounce = false
	 
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
	 
if debounce == false then
	  debounce = true --Now your code will not run, because debounce is not false.
	 
	   mouse.KeyDown:connect(function(key)
	       if key == "e" then
	         print("Pressed e")
	       wait(5)
			print("yes")
	       debounce = false --Now your code will run again.
	   end
	   end)
end
