How to make a script only run if they have a gamepass?

Im trying to make it so if you own the gamepass a certain local script located in StarterPlayerScripts run. Inside ServerScriptService I have a script that detects when someone joins and then there is a function. I have tried putting the local script into this script, but then i ran into a problem which made it unusable, I think it has to be inside StarterPlayerScripts.

So my question is, is it possible to make a script only run if they own a gamepass?

Here is the script inside ServerScriptService.

local GamepassID = 1234567

game.Players.PlayerAdded:Connect(function(plr)
	local owned = game:GetService("MarketplaceService"):UserOwnsGamePassAsync(plr.UserId,GamepassID)
	local function Check()
		if not plr:WaitForChild("PlayerGui"):FindFirstChild(script:GetChildren()[1]:Clone().Name) and game:GetService("MarketplaceService"):UserOwnsGamePassAsync(plr.UserId,GamepassID) then
			script:GetChildren()[1]:Clone().Parent = plr:WaitForChild("PlayerGui")
		end
	end
	plr.CharacterAdded:Connect(Check)
	Check()
end)

Here is the local script, its a double jump script.

local UserInputService = game:GetService("UserInputService")
local localPlayer = game.Players.LocalPlayer
local character
local humanoid 
local canDoubleJump = false
local hasDoubleJumped = false
local oldPower
local TIME_BETWEEN_JUMPS = 0.08
local DOUBLE_JUMP_POWER_MULTIPLIER = 1.2

function onJumpRequest()
if not character or not humanoid or not character:IsDescendantOf(workspace) or humanoid:GetState() == Enum.HumanoidStateType.Dead then
print ("yes")
end

if canDoubleJump and not hasDoubleJumped then
hasDoubleJumped = true
humanoid.JumpPower = oldPower * DOUBLE_JUMP_POWER_MULTIPLIER
humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
end
end
local function characterAdded(newCharacter)
character = newCharacter
humanoid = newCharacter:WaitForChild("Humanoid")
hasDoubleJumped = false
canDoubleJump = false
oldPower = humanoid.JumpPower

humanoid.StateChanged:connect(function(old, new)
if new == Enum.HumanoidStateType.Landed then
canDoubleJump = false
hasDoubleJumped = false
humanoid.JumpPower = oldPower
elseif new == Enum.HumanoidStateType.Freefall then
wait(TIME_BETWEEN_JUMPS)
canDoubleJump = true
end
end)
end
if localPlayer.Character then
characterAdded(localPlayer.Character)
end

localPlayer.CharacterAdded:connect(characterAdded)
UserInputService.JumpRequest:connect(onJumpRequest)

Thanks for your help!

First you can disable the LocalScript in the properties, then you can script

LocalScript.Disabled = false

In the if player owns the gamepass thing

idk if this helps, im just bored...
