If you want to get the email list of the participants who attended the workshop, you need to get in touch with the community team. However, this list can be provided to you once the workshop is hosted. You can ask the community team details about the attendees by sending them your workshop information at firstname.lastname@example.org. The turnover time for the entire activity is 48 hours.
If you want to get the email address of the attendees before starting the workshop, you should mention this while getting the workshop listed. Currently, the registration will remain open up until 15 minutes before the workshop. Hence, in this case, the list may not comprise the details of every attendee.
