How to add FaceTemplate to Avatar Editor?

I am wondering how I can grab the FaceTemplate to allow users to change their faces. I have the ShirtsTemplate and PantsTemplate already but I'd like to know how to add the FaceTemplate, if there is one. I have tried looking this up but I am not finding anything that can help me.

Here is the code, notice that there is no facetemplate to grab the face from the catalog:

if not workspace:FindFirstChild("AvatarEvent") then
	local event = Instance.new("RemoteEvent")
	event.Name = "AvatarEvent"
	event.Parent = workspace
end
local event = workspace.AvatarEvent
local insertS = game:GetService("InsertService")

event.OnServerEvent:Connect(function(player, id)
	local number = tonumber(id)
	if not number then return end
	local asset
	local char = player.Character
	local success = pcall(function()
		asset = insertS:LoadAsset(number)
	end)
	
	if not success then return end
	local child = asset:GetChildren()
	for _,v in pairs(child) do
		if v:IsA("Accessory") then
			char.Humanoid:AddAccessory(v)
		elseif v:IsA("Shirt") then
			local templ = v.ShirtTemplate
			char.Shirt.ShirtTemplate = templ
		elseif v:IsA("Pants") then
			local templ = v.PantsTemplate
			char.Pants.PantsTemplate = templ
		end
	end
	asset:Destroy()
end)

Faces are handled through Decals. So you can easily just have a decal that you can change the .Texture to the AssetId of the image of the face you want.
