Reply to arriving email automatically

Hello Community,

We’re working on a business process where we capture an incoming email to a specific mailbox.

We’ve set up an automated reply to this email, and the reply itself is working ( we implemented the functionality based on the out-of-the-box “Send email to case contact” process). However, the issue is that the reply doesn’t appear in the same thread as the original email. It’s being sent as a new, separate email instead.
