The process begins with the `Gmail Trigger` node, which monitors your Gmail inbox and triggers the workflow whenever a new email arrives.\n\nOnce an email is detected, the `Set Gmail Headers Here` node extracts the email headers from the detected email and organizes them into a standardized format as an object called `headers`. This prepares the email data for further processing in subsequent sections of the workflow.
