How do I make a text that shows the CPS?

local userInputService = game:GetService("UserInputService") -- get UIS service so you can detect when player clicks the LMB

local textLabel = script.Parent.TextLabel -- change to path of textLabel
local clicks = 0 -- set up variable for number of clicks

userInputService.InputBegan:Connect(function(input) -- detect when player inputs something 
    if input.UserInputType == Enum.UserInputType.MouseButton1 then -- check if input is LMB
        clicks += 1 -- add 1 to number of clicks
    end
end)

while wait(1) do -- loop function every second
    textLabel.Text = clicks -- change text to number of clicks
    clicks = 0 -- reset clicks to 0
end
