How to Get My Replies on an email using MailKit library?

Question

I am using MailKit Library to fetch messages from an IMAP Server.

I tried to get an email based on its Subject, but it only returns Client Messages' IDs without my replies

var uidsX = client.Inbox.Search (SearchQuery.SubjectContains ("Message\'s Subject"));

I also tried to hard-code my message id header's value after getting it from Gmail, but i received an Empty List!

const string myReplyId = @"<CAAWrOQmJib_RHUn+3vB9GqATim165zq_Upn_8OTatZZMYGtf5w@mail.gmail.com>";
var myReply = client.Inbox.Search(SearchQuery.HeaderContains("Message-ID", myMessageId));

I even tried to See if i can find my replies in Sent Folder Instead of Inbox, but i'm getting an empty List.

So could any One help me in this?

Here's how I'm doing it using MailKit. Replace msg with the inbox folder message you want to get a reply to.

MessageSummaryItems pullSummaries = MessageSummaryItems.Envelope | MessageSummaryItems.Flags | MessageSummaryItems.InternalDate | MessageSummaryItems.Size | MessageSummaryItems.UniqueId | MessageSummaryItems.GMailLabels | MessageSummaryItems.BodyStructure;

//Open the sent mailbox
await ((ImapFolder)Client.GetFolder(SpecialFolder.Sent)).OpenAsync(FolderAccess.ReadOnly, CancelToken.Token);

//Query the message by the InReplyTo header
var replMsg = await SentFolder.SearchAsync(SearchQuery.HeaderContains("In-Reply-To", msg.Envelope.MessageId));
if (replMsg.Count() > 0)
{
   var replFetch = await SentFolder.FetchAsync(replMsg, pullSummaries);
   foreach (var sentItem in replFetch)
   {
      MimeMessage RepliedEmail = await SentFolder.GetMessageAsync(sentItem.Index);
      Console.WriteLine($"{RepliedEmail.Subject} from {string.Join(",", RepliedEmail.From.OfType<MailboxAddress>().Select(f => $"{f.Name} <{f.Address}>").ToArray())}");
      Console.WriteLine($"{RepliedEmail.GetTextBody(MimeKit.Text.TextFormat.Plain)}");
   }
                            
}
