How can I download updated content in Unity addressable cloud?

Hello everyone,
I was able to download my content using addressable cloud (3.19 GB). Now, when I make an update in one of my groups, I want to download this update, how can I do this? The codes I wrote are as I mentioned below;

using System.Collections;
using System.Collections.Generic;
using System.Linq;
using TMPro;
using UnityEngine;
using UnityEngine.AddressableAssets;
using UnityEngine.UI;

public class DownManager : MonoBehaviour
{
    [Header("UI")]
    public GameObject waitMassage;
    public GameObject downMassage;
    public Slider downSlider;
    public TextMeshProUGUI sizeInfoText;
    public TextMeshProUGUI downValText;
    public GameObject restartPanel;

    [Header("Label")]
    public AssetLabelReference preload;

    private long patchSize;
    private Dictionary<string, long> patchMap = new Dictionary<string, long>();
    void Start()
    {
        restartPanel.SetActive(false);
        waitMassage.SetActive(true);
        downMassage.SetActive(false);
        StartCoroutine(Initaddressable());
        StartCoroutine(CheckUpdateFiles());
    }
    void ClearCache()
    {
        var handle = Addressables.ClearDependencyCacheAsync(preload,false);
        handle.Completed += operation =>
        {
            if (operation.Status==UnityEngine.ResourceManagement.AsyncOperations.AsyncOperationStatus.Succeeded)
            {
                Debug.Log("Cache Cleared successfully!");

            }
            else
            {
                Debug.Log("An error occured: "+operation.OperationException.Message);
            }
        };
    }

    {
        var labels = new List<string>() { preload.labelString };
        patchSize = default;
        foreach (var label in labels)
        {
            var handle = Addressables.GetDownloadSizeAsync(label);

            yield return handle;
            if (handle.Result > 0)
            {
                Debug.Log(label);
            }
            patchSize += handle.Result;
        }
        if (patchSize > decimal.Zero)
        {
            waitMassage.SetActive(false);
            downMassage.SetActive(true);
            sizeInfoText.text = GetFileSize(patchSize);
        }
        else
        {
            downValText.text = " 100 % ";
            downSlider.value = 1f;
            yield return new WaitForSeconds(2f);
            LoadingManager.LoadScene("MainMenu");
        }
    }
    IEnumerator Initaddressable()
    {
        var init = Addressables.InitializeAsync();
        yield return init;
    }
