? I Have A Script That Detects If Someone Has An Item In Their Inventory. [More Info In Desc]

I Have A Script That Detects If Someone Has An Item In Their Inventory. The Only Thing Is, It Checks If They Have The Item In Their Inventory, If They Do, Nothing Happens But If They Don't, They Get An Item. The Only Thing Is, Players Can Bypass This By Equipping The Item First. Is there Anyway To Stop This?

local enabled = true

game.Players.PlayerAdded:Connect(function(p)
	script.Parent.Touched:Connect(function()
		if not p.Backpack:FindFirstChild("InfluencerLauncher") or p.Character.InfluencerLauncher then
			if enabled == true then
				game.ServerStorage.InfluencerLauncher:Clone().Parent = p.Backpack
				enabled = false
				script.Parent.Transparency = 1
				wait(30)
				enabled = true
				script.Parent.Transparency = 0
			end
		end
	end)
end)
