How to make a coutdown when countdown finish player get kicked?

You know what means from the title

anyway here the code

when the count down gets to 0 it stops the code from counting lower than 0 that's why enable = nil, I don't want to change anything of the code I want how to make the player get kicked?

local player = game.Players.LocalPlayer
enable = true


script.Parent.MouseLeave:Connect(function()
    repeat wait() until script.Parent.Text == "0"
    if script.Parent.Text == "0" then
        while script.Parent.MouseMoved do
            enable = nil
                script.Parent.Text = ("0")
            player:Kick("Count down ended")
        end
    end
end)
