How Can I Download Multiple Files With Unity Web Request?

Question

I want to download multiple files with different extension file types from the server with unitywebrequest and show progress with progress bar. maybe I need a list or dictionary to add my files URL, but how? I can do it with one file by this code:

public class Tmp_FileDownloader : MonoBehaviour
{
    public TextMeshPro m_downloadProgress;
    private UnityWebRequest uwr;

    public string downloadUrl;
    void Start()
    {
        StartCoroutine(DownloadFile());
    }

    IEnumerator DownloadFile()
    {
        var uwr = new UnityWebRequest("http://localhost/1.mp4", UnityWebRequest.kHttpVerbGET);
        string path = Path.Combine(Application.persistentDataPath, "1.mp4");

        uwr.downloadHandler = new DownloadHandlerFile(path);

        StartCoroutine(ShowDownloadProgress(uwr));

        yield return uwr.SendWebRequest();
        if (uwr.isNetworkError || uwr.isHttpError)
            Debug.LogError(uwr.error);
        else
        {
            m_downloadProgress.text = (string.Format("{0:P1}", uwr.downloadProgress));
            Debug.Log("File successfully downloaded and saved to " + path);
        }
    }

    public IEnumerator ShowDownloadProgress(UnityWebRequest www)
    {
        while (!www.isDone)
        {
            Debug.Log(string.Format("Downloaded {0:P1}", www.downloadProgress));
            m_downloadProgress.text = (string.Format("{0:P1}", www.downloadProgress));
            yield return new WaitForSeconds(.01f);
        }
        Debug.Log("Done");
    }
}
