Axe Tool animation does not animate the tool

[Elaugh14 (zeke)]

I made an animation and animated the arm to move up and the axe to be behind the players neck like this:

But instead it does this:

that is because it is not animated the tool and just keeps it normal for some reason

please help

local tool = script.Parent
local players = game:GetService("Players")
local player = players.LocalPlayer

local idleAnimId = "rbxassetid://84491416188289"
local idleTrack = nil
local character = nil
local humanoid = nil

tool.Equipped:Connect(function()
	character = player.Character or player.CharacterAdded:Wait()
	humanoid = character:FindFirstChildOfClass("Humanoid")

	if humanoid then
		local idleAnim = Instance.new("Animation")
		idleAnim.AnimationId = idleAnimId
		idleTrack = humanoid:LoadAnimation(idleAnim)
		idleTrack.Priority = Enum.AnimationPriority.Idle
		idleTrack:Play()
	end
end)

tool.Unequipped:Connect(function()
	if idleTrack then
		idleTrack:Stop()
		idleTrack = nil
	end
end)

It is also supposed to be an idle anim so it does not move

I had to change the position and rotation of the axe in starterpack because it does not animate it
