How can I place the cloned arm into the workspace?

Im a beginner scripter so i might not understand everything. i want to make the fake arm is visible when fully zoomed/firstperson. this is in a script btw should i put it in a local script?

game.Players.PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function(character)
		
		local rightArm = character:WaitForChild("Right Arm")
		local rightArmClone = rightArm:Clone()
		local model = Instance.new("Model", character)
			
		rightArmClone.Parent = model
		rightArmClone.FormFactor = "Custom"
		rightArmClone.Size = Vector3.new(0.99, 1.99, 0.99)
			
		local weld = Instance.new("Weld")
		weld.Parent = rightArm
		weld.Part0 = rightArm
		weld.Part1 = rightArmClone
	end)
end)

do this:

rightArmClone.Parent = game.Workspace
