How do i preload an animation?

local ContentProvider = game:GetService("ContentProvider")

local anim = "rbxassetid://3965998277"

local animation = Instance.new("Animation")
animation.AnimationId = anim


spawn(function()
local asset = {anim}
ContentProvider:PreloadAsync(asset)
print("loaded")
end)
print("xd")
game.ReplicatedStorage.hit1.OnServerEvent:Connect(function(player)
	local anims = player.Character.Humanoid:GetPlayingAnimationTracks()
	for i, track in pairs (anims) do
		track:Stop()
	end
	local anim2 = player.Character.Humanoid:LoadAnimation(animation)
	anim2:Play()
end)

I'm attempting to preload the animation, because it doesn't work in game at the moment.
