How to make an individual playerzone

Trying to make it so that when a player hovers over another player they can see the player’s zone(and the zone moves around with them). I tried using an attachment but this just doesn’t show when in game. Are there any other ways to do this? My code:

local function showKillzone(target)
	
	if target.Parent:FindFirstChild("Humanoid") then
		
		if selectedTarget == target.Parent then return end
		
		--destroyAttachment(selectedTarget)
		
		local attachment = Parts.Part.Attachment:Clone()
		attachment.Parent = target.Parent:FindFirstChild("LeftLowerLeg")
		
		attachment.Killzone.Anchored = true
		attachment.Killzone.Name = "Killzone"
		
		selectedTarget = target.Parent
		
		print(target.Parent)
	end
end

mouse.Move:Connect(function()
	local target = mouse.Target
	if not target then return end	
	showKillzone(target)
end)
