Youtube API upload video and add audio from the free library (C#)

Question

What I want to do is , after uploading the video , I want to add audio to the video from the free audio that you can add in the creator studio. I can do it manually by editing the video and go to the audio section but i want that the software will do it. this is my code now for uploading video to youtube:

UserCredential credential;
        using (var stream = new FileStream("client_id.json", FileMode.Open, FileAccess.Read))
        {
            credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                // This OAuth 2.0 access scope allows an application to upload files to the
                // authenticated user's YouTube channel, but doesn't allow other types of access.
                new[] { YouTubeService.Scope.YoutubeUpload },
                "user",
                CancellationToken.None
            );
        }

        var youtubeService = new YouTubeService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
        });

        var video = new Video();
        video.Snippet = new VideoSnippet();
        video.Snippet.Title = "title";
        video.Snippet.Description = "description";
        video.Snippet.Tags = new string[]{"tags"};
        video.Snippet.CategoryId = "22"; 
        video.Status = new VideoStatus();
        video.Status.PrivacyStatus = "public"; 
        var filePath = "video.avi"

        using (var fileStream = new FileStream(filePath, FileMode.Open))
        {
            var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");
            videosInsertRequest.ProgressChanged += videosInsertRequest_ProgressChanged;
            videosInsertRequest.ResponseReceived += videosInsertRequest_ResponseReceived;

            await videosInsertRequest.UploadAsync();
        }

I just need to add audio to the uploaded youtube from the creator studio programmatically. help is appreciated.

There is no such method from the Youtube API. You can see the supported methods in the Videos reference.

Update: The method is available here YouTube > Data API > Reference > Videos: insert
