Add Data Store Function to Inventory#2

Hi everyone I’m currently working on an Inventory System and it saves the Tools when I die(cuz I have set reset on Spawn to false) but when I leave and join again the Tools disappear(not sure if I should show a photo of that)
Now what I need is a Data Store function that saves my Data Tools when I leave and I have no Idea how to do that but I believe it’s easy(I searched on other Platforms for the Solution but it wasn’t exactly what I needed I got 2 Scripts here:
(and I asked for this before but no one really helped me)

--InventoryScript:

local inventoryEvent = game.ReplicatedStorage.Remotes.InventoryEvent

game.Players.PlayerAdded:Connect(function(player)
	
	local inventory = player:WaitForChild("Inventory")
	
	local inventoryFrame = player.PlayerGui:WaitForChild("InventoryGui").InventoryFrame.ItemsFrame:GetChildren()
	
	inventory.ChildAdded:Connect(function(Item)
		inventoryEvent:FireClient(player, Item.Name, true)
	end)
end)

inventoryEvent.OnServerEvent:Connect(function(player, ItemName, Value, button)
	
	 if Value == false then
			local SelectedItem = player.Inventory:FindFirstChild(ItemName)
			local backpack = player.Backpack:GetChildren()
			local stuff = player.Character:GetChildren()
			
			if #backpack == 0 and not player.Character:FindFirstChildWhichIsA("Tool") then
				button.Text = "Unequip"
				button.BackgroundColor3 = Color3.new(255,0,0)
				SelectedItem:Clone().Parent = player.Backpack
			else
				for i,v in ipairs(backpack) do
					button.Text = "Equip"
					button.BackgroundColor3 = Color3.new(0,255,0)
					v:Destroy()
				end
				for i, v in ipairs(stuff) do
					if v:IsA("Tool") then
						button.Text = "Equip"
						button.BackgroundColor3 = Color3.new(0,255,0)
						v:Destroy()
					end
				end
			end
	 end
end)


–InventoryLocalScript(Baba Boi)

local InventoryEvent = game.ReplicatedStorage.Remotes.InventoryEvent
local itemFrame = script.Parent:FindFirstChild(“ItemsFrame”)

InventoryEvent.OnClientEvent:Connect(function(ItemName, Value)
if Value == true then

local ItemButton = script.Parent.ItemsFrame.ItemButton:Clone()
ItemButton.Visible = true
ItemButton.Name = ItemName
ItemButton.Text = ItemName
ItemButton.Parent = itemFrame

local equipButton = script.Parent.EquipFrame["EquipButton"]

	ItemButton.MouseButton1Click:Connect(function()
		script.Parent.EquipFrame.Title.Text = ItemName
		script.Parent.EquipFrame.Title.Visible = true
		equipButton.Visible = true
	end)

end

end)
