How would I add a creator tag to this?

I'm new to scripting and don't really understand the creator tags

local tool = script.Parent

local idleAnim = script:WaitForChild("Idle")
local idleAnimTrack
local swingAnim = script:WaitForChild("Swing")
local swingAnimTrack

local slashSound = script:WaitForChild("SlashSound")
local sheathSound = script:WaitForChild("SheathSound")
local hitSound = script:WaitForChild("HitSound")

local hitCharacters = {}
local debounce = false


tool.Equipped:Connect(function()

	local humanoid = script.Parent.Parent.Humanoid
	if not idleAnimTrack then idleAnimTrack = humanoid:LoadAnimation(idleAnim) end

	idleAnimTrack:Play()

	sheathSound:Play()
end)
tool.Unequipped:Connect(function()

	if idleAnimTrack then idleAnimTrack:Stop() end
	if swingAnimTrack then swingAnimTrack:Stop() end

	sheathSound:Play()
end)
tool.Activated:Connect(function()

	if debounce then return end
	debounce = true

	local humanoid = script.Parent.Parent.Humanoid
	if not swingAnimTrack then swingAnimTrack = humanoid:LoadAnimation(swingAnim) end

	swingAnimTrack:Play()

	wait(0.5)   
	slashSound:Play()

	wait(0.5)
	debounce = false
end)
tool.Blade.Touched:Connect(function(touch)

	if hitCharacters[touch.Parent] or not debounce then return end
	if touch.parent:FindFirstHumanoid("Players") then return end
	if touch.Parent:FindFirstChild("Humanoid") then

		if touch.Name == "Head" then
			touch.Parent.Humanoid:TakeDamage(4)
		else
			touch.Parent.Humanoid:TakeDamage(3)
		end
		hitSound:Play()
		hitCharacters[touch.Parent] = true
		wait(1)
		hitCharacters[touch.Parent] = nil
	end
end)

Destroy all existing tags & add a new one with the player as a value. The creator tag is an ObjectValue.

local function TagHumanoid(Attacker: Player, Target: Humanoid)
	for index, value in pairs(Humanoid:GetChildren()) do
		if value:IsA("ObjectValue") and string.lower(value.Name) == "creator" then
			value:Destroy()
		end
	end
	local ObjectValue = Instance.new("ObjectValue")
	ObjectValue.Name = "creator"
	ObjectValue.Value = Attacker
	ObjectValue.Parent = Humanoid
end
