How to set content Type while using blob data movement library c#

Question

I want to transfer my local folder to azure blob for that I have used this movement nuget from azure docs website link

code from section - Transfer a local directory to Blob storage works perfectly fine and upload all folder to blob but problem is all file content-type is application/octet it should take its own default content type like if its html it should uplaod html file content as text/html

What should be done? pls guide.

public static async Task TransferLocalDirectoryToAzureBlobDirectory(CloudStorageAccount account)
{
    string localDirectoryPath = GetSourcePath();
    CloudBlobDirectory blobDirectory = GetBlobDirectory(account);
    TransferCheckpoint checkpoint = null;
    DirectoryTransferContext context = GetDirectoryTransferContext(checkpoint);
    CancellationTokenSource cancellationSource = new CancellationTokenSource();
    Console.WriteLine("\nTransfer started...\nPress 'c' to temporarily cancel your transfer...\n");

    Stopwatch stopWatch = Stopwatch.StartNew();
    Task task;
    ConsoleKeyInfo keyinfo;
    UploadDirectoryOptions options = new UploadDirectoryOptions()
    {
        Recursive = true
    };

    try
    {
        task = TransferManager.UploadDirectoryAsync(localDirectoryPath, blobDirectory, options, context, cancellationSource.Token);
