When Developer Product Bought, Teleport to a part?

I Need a lot of help whit this. I Wanted to Make a screenGui that the game is closed but you could buy access to the game when you are over the void on a checkpoint. I want it to teleport you to the entrance of the game when you bought it + deleting the screen gui that says that the game is closed.

Here Is My Explorer, If you want more info on this make sure to tell me in the Comments. Image Of My Explorer In New Tab

My Script From The Image (In ServerScriptService):

local MarketPlaceService = game:GetService('MarketplaceService')
local id = 448687322

MarketPlaceService.ProcessReceipt = function(receiptInfo)
	for i, player in ipairs(game.Players:GetChildren()) do
		if player.userId == receiptInfo.PlayerId then
			if receiptInfo.ProductId == id then
				--Teleport To Part
			end
		end
	end
end

Please Help Me!
