send email on same thread.
Problem
I have received a successful response of a email using gmail.users.messages.send() which is like `{ "id": "1231212312", "labelIds": ["UNREAD", "SENT", "INBOX"], "threadId": "23123123" }` I need to send an email again to the same email address but on the same thread not as a new email i.e using thread id to send email. Need Help!

Send Email in Existing Thread Using Gmail API
When sending an email using the Gmail API, if the 'threadId' parameter is not included or incorrectly specified, the email will be sent as a new message rather than as a reply in the existing thread. To ensure the email is sent in the same thread, the correct 'threadId' must be provided in the request.

Prepare the Email Message
Create the email message in the required format. Ensure to include the 'threadId' from the previous email response to maintain the conversation thread.
javascriptconst email = 'From: sender@example.com\r\nTo: recipient@example.com\r\nSubject: Re: Your Subject\r\nIn-Reply-To: <previous-message-id>\r\nReferences: <previous-message-id>\r\n\r\nYour email body here.'; - 2
Base64 Encode the Email
The email message must be base64url encoded before sending it through the Gmail API. This is necessary to ensure the message is properly formatted.
javascriptconst base64EncodedEmail = Buffer.from(email).toString('base64url'); - 3
Send Email Using Gmail API
Use the 'gmail.users.messages.send' method to send the email. Make sure to include the 'threadId' from the previous email response in the request body.
javascriptconst request = {\n 'raw': base64EncodedEmail,\n 'threadId': '23123123'\n};\n\ngmail.users.messages.send({\n userId: 'me',\n resource: request\n}); - 4
Handle API Response
Check the response from the API call to ensure the email was sent successfully. If the response contains an 'id', the email was sent correctly in the same thread.
javascriptgmail.users.messages.send(request).then(response => {\n console.log('Email sent successfully:', response.data.id);\n}).catch(error => {\n console.error('Error sending email:', error);\n});
Validation
To confirm the fix worked, check the Gmail inbox of the recipient to see if the new email appears as a reply in the same thread. Additionally, verify the response from the API call contains a valid 'id' indicating successful sending.
