How to create a [e dance2] button?

I'm making a obby game and am wondering if there is a way to make a player e dance2 by pressing a GUI button.

I have been looking for ways to add animation to the game.

All I have is

local Players = game:GetService("Players")

local player = Players:FindFirstChild("Builderman")

local character = player.Character 
local humanoid = character:FindFirstChild("Humanoid")

local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/asset/?id=507771019" -- Roblox dance emote

local animationTrack = humanoid:LoadAnimation(animation)
animationTrack:Play()

I just can't find the ID for e dance 2 anywhere.
