How do I hook up leaderstats to save with a moduleScript?

Hallo again!

I’m trying to make a way for my game to save how many times they beat an obstacle course. I’ve made a script to make the leaderstats:

local Players = game:GetService("Players")
local DataStoreSevice = game:GetService("DataStoreService")
local winstore = DataStoreSevice:GetDataStore("PlayerWins")

local function setupleaderboard(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local wins = Instance.new("IntValue")
	wins.Name = "Wins"
	wins.Value = 0
	wins.Parent = leaderstats
end

--Trigger
game.Players.PlayerAdded:Connect(setupleaderboard)

A script to increase their wins by 1 when they reach the end:

local Players = game:GetService("Players")
local winners = {}

local function OnHit(object)
	local objectparent = object.Parent
	local h = object.Parent:FindFirstChild("Humanoid")
	if h then
		object.Parent.HumanoidRootPart.CFrame = CFrame.new(Vector3.new(13.65, 2.8, -5.05))
		local player = Players:GetPlayerFromCharacter(objectparent)
		local leaderstats = player.leaderstats
		local winstat = leaderstats and leaderstats:FindFirstChild("Wins")
		if winstat then
			winstat.Value = winstat.Value + 1
			table.insert(winners, objectparent)
		end
	end
end

script.Parent.Touched:Connect(OnHit)

And a script to make a datastore. (Mostly copied from DevHub :P)

-- Set up table to return to any script that requires this module script
local PlayerStatManager = {}

local DataStoreService = game:GetService("DataStoreService")
local playerData = DataStoreService:GetDataStore("PlayerData")

-- Table to hold player information for the current session
local sessionData = {}

local AUTOSAVE_INTERVAL = 60

-- Function that other scripts can call to change a player's stats
function PlayerStatManager:ChangeStat(player, statName, value)
	local playerUserId = "Player_" .. player.UserId
	assert(typeof(sessionData[playerUserId][statName]) == typeof(value), "ChangeStat error: types do not match")
	if typeof(sessionData[playerUserId][statName]) == "number" then
		sessionData[playerUserId][statName] = sessionData[playerUserId][statName] + value
	else
		sessionData[playerUserId][statName] = value
	end
end

-- Function to add player to the "sessionData" table
local function setupPlayerData(player)
	local playerUserId = "Player_" .. player.UserId
	local success, data = pcall(function()
		return playerData:GetAsync(playerUserId)
	end)
	if success then
		if data then
			-- Data exists for this player
			sessionData[playerUserId] = data
		else
			-- DataStore is working, but this player is new.
			sessionData[playerUserId] = {Wins = 0}
		end
	else
		warn("Cannot access data store.")
	end
	
end

local function savePlayerData(playerUserId)
	if sessionData[playerUserId] then
		local tries = 0
		local success
		repeat
			tries = tries + 1
			success = pcall(function()
				playerData:SetAsync(playerUserId, sessionData[playerUserId])
			end)
			if not success then wait(1) end
		until tries == 3 or success
		if not success then
			warn("Cannot save data!")
		end
	end
end

local function SaveOnExit(player)
	local playerUserId = "Player_" .. player.UserId
	savePlayerData(playerUserId)
end

local function autoSave()
	while wait (AUTOSAVE_INTERVAL) do
		for playerUserId, data in pairs(sessionData) do
			savePlayerData(playerUserId)
		end
	end
end

-- Connect "setupPlayerData()" function to "PlayerAdded" event
game.Players.PlayerAdded:Connect(setupPlayerData)

game.Players.PlayerRemoving:Connect(SaveOnExit)

return PlayerStatManager

How do I save the leaderstat “Wins” to the datastore, so when a player leaves and rejoins, they have the same amount of wins as before? Sorry if I’m doing this wrong, I’m a new developer.
