This feature allows organizer to show deleted tickets screen on app or not.
How it works?
Once a ticket is deleted with visibility TRUE ("showDeletedTicket":true), user can see this ticket under Deleted tickets screen. If visibility is FALSE, deleted ticket will not appear on app.
To enable/disable Deleted tickets tab on app, go to Application feature, set Deleted Tickets Visibility to true/false
By default, value is false (no Deleted tickets tab on app)
