How to include original email as a quote in a Email Direct Reply in a Workflow (Helpdesk)

Hi. I have an automatic email with a couple placeholders, sent to the recipient stating what their ticket number is in a Workflow in Zoho Desk. What I would like to do is quote the original email they sent which triggers the workflow at the bottom of the email that is generated to them. How would I do so?

Thank you very much.
