How do I check if someone has a gamepass?

Hello there, I want to make a game where if someone has a VIP game pass it then will run a script, I've tried this before

local marketPlaceService = game:GetService("MarketplaceService")
local player = game.Players.LocalPlayer
local gamePassId = --// I am not acctually going to put my gamepass id here)

if marketPlaceService:UserOwnsGamePassAsync(player, gamePassId) then
	print("USER OWNS GAMEPASS")
else
	print("USER DOESN'T OWN GAMEPASS")
end

It doesn't work (I PUT MY GAMEPASSID THERE BTW NOT SENDING IT THO)

The marketPlaceService:UserOwnsGamePassAsync function requires the user ID of the player to check for, not the player instance.
