How can i include bind to close in this script?

local dss = game:GetService("DataStoreService")
local toolsDS = dss:GetDataStore("IIII")
local toolsFolder = game.ServerStorage.ShopItems

game.Players.PlayerAdded:Connect(function(plr)

	local toolsSaved = toolsDS:GetAsync(plr.UserId .. "-tools") or {}

	for i, toolSaved in pairs(toolsSaved) do
		if toolsFolder:FindFirstChild(toolSaved) then 

			toolsFolder[toolSaved]:Clone().Parent = plr.Backpack
			toolsFolder[toolSaved]:Clone().Parent = plr.StarterGear 
		end
	end

	plr.CharacterRemoving:Connect(function(char)

		char.Humanoid:UnequipTools()
	end)
end)

game.Players.PlayerRemoving:Connect(function(plr)

	local toolsOwned = {}

	for i, toolInBackpack in pairs(plr.Backpack:GetChildren()) do
		table.insert(toolsOwned, toolInBackpack.Name)
	end

	local success, errormsg = pcall(function()
		toolsDS:SetAsync(plr.UserId .. "-tools", toolsOwned)


	end)
	if errormsg then warn(errormsg) end
end)

The code you have should not yield, so you can put any new code at the bottom for binding something to close.

local dss = game:GetService("DataStoreService")
local toolsDS = dss:GetDataStore("IIII")
local toolsFolder = game.ServerStorage.ShopItems
local RunService = game:GetService("RunService")
local Players = game:GetService("Players")

game.Players.PlayerAdded:Connect(function(plr)

	local toolsSaved = toolsDS:GetAsync(plr.UserId .. "-tools") or {}

	for i, toolSaved in pairs(toolsSaved) do
		if toolsFolder:FindFirstChild(toolSaved) then 

			toolsFolder[toolSaved]:Clone().Parent = plr.Backpack
			toolsFolder[toolSaved]:Clone().Parent = plr.StarterGear 
		end
	end

	plr.CharacterRemoving:Connect(function(char)

		char.Humanoid:UnequipTools()
	end)
end)

game.Players.PlayerRemoving:Connect(function(plr)

	local toolsOwned = {}


	for i, toolInBackpack in pairs(plr.Backpack:GetChildren()) do
		table.insert(toolsOwned, toolInBackpack.Name)
	end

	local success, errormsg = pcall(function()
		toolsDS:SetAsync(plr.UserId .. "-tools", toolsOwned)


	end)
	if errormsg then warn(errormsg) end
end)

local toolsOwned = {}

game:BindToClose(function(plr)
	if not RunService:IsStudio() and #Players:GetPlayers() > 1 then
		for _, player in ipairs(Players:GetPlayers()) do
			coroutine.wrap(plr.UserId .. "-tools", toolsOwned)(player)
		end
	end
end)
