How can I enable a script in the player's character using a gamepass script?

I have been trying to figure this out for about 3-4 days now and it hasn't worked. I've tried putting the script in startercharacters, and in starterplayers, but nothing works. Here are the scripts I've attempted to use:

script no. 1 (modified "gamepass admin tools" script)

-- Waits for parent.child to exist, then returns it
local function WaitForChild(parent, childName)
    assert(parent, "ERROR: WaitForChild: parent is nil")
    while not parent:FindFirstChild(childName) do parent.ChildAdded:wait() end
    return parent[childName]
end

local MarketplaceService = Game:GetService('MarketplaceService')
local PlayersService = Game:GetService('Players')
local InsertService = Game:GetService('InsertService')


local GamePassIdObject = WaitForChild(script, 'GamePassId')


function onPlayerEntered(player)

if MarketplaceService:PlayerOwnsAsset(player, GamePassIdObject.Value) then

game.Players.PlayerAdded:connect(function(plr)
plr.CharacterAdded:connect(function(char)
local weapon = char:WaitForChild('MetroidWeapons')
weapon.Disabled = false

end)
end)
end
end




game.Players.ChildAdded:connect(onPlayerEntered)

script no. 2

local id = 4440659
local player = game.Player.LocalPlayer

if game:GetService("MarketplaceService"):PlayerOwnsAsset(player, id) then
game.Players.LocalPlayer.Character.MetroidWeapons.Disabled = false -- if player have the Pass, the script is enabled.
else
game.Players.LocalPlayer.Character.MetroidWeapons.Disabled = true -- if player don't have the Pass, the script is disabled.
end

Script no. 3 (placed in startercharacterscripts)

local id = 4440659
local player = game.Player.LocalPlayer

if game:GetService("MarketplaceService"):PlayerOwnsAsset(player, id) then

script.Parent.MetroidWeapons.Disabled = false -- if player have the Pass, the script is enabled.
else
script.Parent.MetroidWeapons.Disabled = true -- if player don't have the Pass, the script is disabled.

end
