You can share your ticket page with other members of the team without having to give them access to Survey2Connect account. Share button on the Tickets page creates a link that you can share with others and they will be able to view the ticket overview page, agent performance page, survey performance page.
Share option only shares the ticket page in read-only mode. Other people accessing the link would only be able to view the ticket page. This is how it would appear to others when the share link would be accessed.
