How do I add custom animation to tool?

How do I add a custom animation to my tool? I am scripting a cafe and I made the model and tool for my cup and made the animation. How do I make it so that when the player is holding it, and you click, it plays the animation? Please help! <3

--This is for when you have it equipped and click with it

local Tool = script.Parent
local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/Asset?ID=144884906" --Replace with your animation
Tool.Activated:connect(function()
local animTrack = Humanoid:LoadAnimation(animation)
animTrack:Play()
end)

--This is for when you equip it and nothing else

local Tool = script.Parent
local animation = Instance.new("Animation")
animation.AnimationId = "http://www.roblox.com/Asset?ID=144884906" --Replace with your animation
Tool.Equipped:connect(function()
local animTrack = Humanoid:LoadAnimation(animation)
animTrack:Play()
end)
