Is there any way to send an email in the same thread?

I'm trying to send emails into one thread so it looks as similar as possible as sending via Gmail web UI.

According to the Gmail documentation, I wrote the next code on Kotlin that works correctly, but not completely

val DEFAULT_CHARSET: String = Charsets.UTF_8.name()

// get headers from original email
val messageId = originalMessage.payload.headers.find { it.name.equals("Message-ID", true) }?.value
val subject = originalMessage.payload.headers.find { it.name.equals("Subject", true) }?.value

// creating message
val message = MimeMessage(Session.getDefaultInstance(Properties()))

message.setFrom(InternetAddress(emailFrom, senderNameFrom, DEFAULT_CHARSET))
message.addRecipient(javax.mail.Message.RecipientType.TO, InternetAddress(emailTo))

message.setSubject(subject, DEFAULT_CHARSET)

// this headers are required accoring to [RFC 2822][1] standard
message.setHeader("In-Reply-To", messageId)
message.setHeader("References", messageId)
message.setHeader("Subject", "Re:$subject")

// creates message part
val messageBodyPart = MimeBodyPart()
messageBodyPart.setContent(content, "text/html; charset=UTF-8")

// creates multi-part
val multipart = MimeMultipart()
multipart.addBodyPart(messageBodyPart)


// sets the multi-part as e-mail's content
message.setContent(multipart)

val buffer = ByteArrayOutputStream()
emailMessage.writeTo(buffer)
val requestMessage = Message()
requestMessage.raw = Base64.encodeBase64URLSafeString(buffer.toByteArray())

// this thread ID you should collect from the original message
requestMessage.threadId = threadId

// from the result variable you can collect id, threadId, labels, etc.
val result = gmail.users().messages().send("me", requestMessage).execute()

As a result, emails send into one thread (inbox looks like this), but there are no three dots "show trimmed content" that hides the content of previous messages:

Is it possible to make it looks like? Other languages and libraries will also suit me.

P.S. I also tried sending emails as a Gmail draft, but this also doesn't work.

Test was done with java-libraries:

• javax.mail:mail:1.5.0-b01
• com.sun.mail:javax.mail:1.6.2
