Why doesn't my animation play when the tool is activated?

I am trying to play an animation with a tool whenever that tool has been activated. When I try, my animation never plays.

local plr = game:GetService("Players").LocalPlayer
local char = plr.Character or plr.CharacterAdded:Wait()
local h = char:WaitForChild("Humanoid")
local anim = h:LoadAnimation(script.Parent:WaitForChild("Animation"))

script.Parent.Activated:connect(function()
    anim:Play()
end)

This code is Local Script in a tool in the starter pack The animation is a child of the tool and has an ID The animation is 1 second long The animations priority is set to [Action]
