There are two questions to ask.

--Script in ServerscriptService
local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
 
local gamePassID = 0000000 -- Change this to your game pass ID
 
local function onPlayerAdded(player)
 
	local hasPass = false
 
	-- Check if the player already owns the game pass
	local success, message = pcall(function()
		hasPass = MarketplaceService:UserOwnsGamePassAsync(player.UserId, gamePassID)
	end)
 
	-- If there's an error, issue a warning and exit the function
	if not success then
		warn("Error while checking if player has pass: " .. tostring(message))
		return
	end
 
	if hasPass == true then
		print(player.Name .. " owns the game pass with ID " .. gamePassID)
		-- Assign this player the ability or bonus related to the game pass
		game.StarterGui.RUN.TextButton.Visible = true
	end

 end
-- Connect 'PlayerAdded' events to the 'onPlayerAdded()' function
Players.PlayerAdded:Connect(onPlayerAdded)

This script is for the "run" gamepass. This script is for outside purchases(or purchased before/ingame)

Does this script makes the button visible to all other players with people who didn't buy the gamepass?

local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
 
local gamePassID = 5923482 -- Change this to your game pass ID
 
local function onPlayerAdded(player)
 
	local hasPass = false
 
	-- Check if the player already owns the game pass
	local success, message = pcall(function()
		hasPass = MarketplaceService:UserOwnsGamePassAsync(player.UserId, gamePassID)
	end)
 
	-- If there's an error, issue a warning and exit the function
	if not success then
		warn("Error while checking if player has pass: " .. tostring(message))
		return
	end
 
	if hasPass == true then
		print(player.Name .. " owns the game pass with ID " .. gamePassID)
		-- Assign this player the ability or bonus related to the game pass
		local GUI = player:WaitForChild("PlayerGui")
		local RUN = GUI:WaitForChild("RUN")
		local button = RUN:WaitForChild("TextButton")
		button.Visible = true
	end

 end
-- Connect 'PlayerAdded' events to the 'onPlayerAdded()' function
Players.PlayerAdded:Connect(onPlayerAdded)



--If I use this code, Output says:
14:53:57.663 - Infinite yield possible on 'Players.S_H1234.PlayerGui:WaitForChild("RUN")'

There is ScreenGUI "RUN" in S_H1234.PlayerGui, but why will it say Infinite yield?

This script is from Official Roblox Developer Forum : Click ME
