Host contact email - Where does this appear?

There is a field for Host contact email under General Configuration. It says: Attendees can use the email address you enter below to contact you. Zoom will continue to contact you through the email address associated with your Zoom account.

Where exactly does this email actually show in the webinar process? Is it in the lobby, emails, etc.? How can attendees respond to the email that you put in this field if the webinar confirmation email comes from Zoom?
