Is this how the command pattern works?

Couple of days ago someone recommended using the command pattern and just now I finished reading a guide and tried implementing it into Roblox and I wanted to know if it was correct.

This command class is probably unnecessary, but made it anyways to follow along with the guide.

local Command = {}
Command.__index = Command

function Command.new()
	local self = setmetatable({},Command)
	return self
end

function Command:Execute()
	-- shouldn't do anything
end

return Command

local Light = {}
Light.__index = Light

function Light.new()
	local self = setmetatable({},Light)
	return self
end

function Light:On()
	print("Light is on")
end

function Light:Off()
	print("Light is off")
end

return Light.new()

local Command = require(script.Parent:WaitForChild("Command"))
local LightOnCommand = setmetatable({},Command)
LightOnCommand.__index = LightOnCommand

function LightOnCommand.new(light)
	local self = setmetatable(Command.new(),LightOnCommand)
	self.light = light
	return self
end

function LightOnCommand:Execute()
	-- print("LightOnCommand:Execute()")
	self.light:On()
end

return LightOnCommand

local UIS = game:GetService("UserInputService")

local Light = require(script.Parent:WaitForChild("Light"))
local LightOnCommand = require(script.Parent:WaitForChild("LightOnCommand"))
local LightOffCommand = require(script.Parent:WaitForChild("LightOffCommand"))

local keyE = LightOffCommand.new(Light)
local keyR = LightOnCommand.new(Light)

UIS.InputBegan:Connect(function(inputObject, gameProcessed)
	if gameProcessed then return end 
	if UIS:IsKeyDown(Enum.KeyCode.E) then keyE:Execute() end
	if UIS:IsKeyDown(Enum.KeyCode.R) then keyR:Execute() end
end)
