does anybody know how to show particle when press button E and disable when press button E?

so I made a lightsaber with particles as the blade, and I want to use the button "E" to enable the particles so they show up and Then "E" to disable it as well.

you can use UserInputService to detect if the player click E and use a Bool value to see if they clicked it before it would look like this

local UserInputService = game:GetService("UserInputService")
local Clicked = false
UserInputService.InputBegan:Connect(function(Input)
	if Input.KeyCode == Enum.KeyCode.E then
		if Clicked then
			Clicked = false
			print("Not On")
		else
			Clicked = true
			print("On")
			--turn on
			--the second time people click E the click variable will be false and turn off
		end
	end
end)
