How i pause the Tweening?

In the Script, with you hold E, a Power Bar start to fill, but i don't know how to Pause the Tweening when the Player stops hold E.

Script:

Ok = false

function SubirForca(inputObject, gameProcessedEvent)
    if inputObject.KeyCode == Enum.KeyCode.E then
        Ok = true
        if Ok == true then
            script.Parent.Forca:TweenSize(UDim2.new(0, 200, 0, 20), "Out", "Linear")
            print("Subindo barra de força")
        end
    end
end

game:GetService("UserInputService").InputBegan:connect(SubirForca)

function ManterForca()
    Ok = false
    print("Força mantida")
end

game:GetService("UserInputService").InputEnded:connect(ManterForca)
