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)
