How to make the animation stop running?

I'm currently new to scripting, so I apologize for my simple mistakes.

I'm making a GUI where you have to click one of the text buttons and an Animation will work. I made the animation work through the MouseButton1Click, but now I'm trying to make it so that once you click the text button again, it will stop.

local btn = script.Parent
local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid",10)
local CanEmote = true
local Cooldown = 1

btn.MouseButton1Click:Connect(function()
	if CanEmote == true then
		Humanoid.JumpPower = 0
		Humanoid.WalkSpeed = 0
		CanEmote = false
		local dance = Humanoid:LoadAnimation(script:FindFirstChild("Anim1"))
		dance:Play()
		
		wait(Cooldown + dance.Length)
		Humanoid.JumpPower = 50
		Humanoid.WalkSpeed = 16
		CanEmote = true
	end
end)

Thank you in advance! :)
