如何向我的C# YouTube视频上载程序添加YouTube本地化(翻译)？

using Google.Apis.Services;
using Google.Apis.YouTube.v3;
using Google.Apis.YouTube.v3.Data;

YouTubeService youtubeService = new YouTubeService(new BaseClientService.Initializer()
{
    ApiKey = "YOUR_API_KEY",
});

Video video = new Video();
video.Snippet = new VideoSnippet();
video.Snippet.Title = "YOUR_VIDEO_TITLE";
video.Snippet.Description = "YOUR_VIDEO_DESCRIPTION";
video.Snippet.Tags = new string[] { "TAG1", "TAG2" };
video.Snippet.DefaultLanguage = "YOUR_VIDEO_DEFAULT_LANGUAGE";
video.Snippet.DefaultAudioLanguage = "YOUR_VIDEO_DEFAULT_AUDIO_LANGUAGE";

video.Localizations = new Dictionary<string, VideoLocalization>();
video.Localizations.Add("LANGUAGE_CODE", new VideoLocalization()
{
    Title = "YOUR_TRANSLATED_TITLE",
    Description = "YOUR_TRANSLATED_DESCRIPTION"
});

VideosResource.InsertRequest insertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "VIDEO_CONTENT_TYPE");
insertRequest.Upload();

string videoId = insertRequest.ResponseBody.Id;
