J'aimerais que les participants puissent modifier leurs données d'inscription, actuellement il n'y a pas de bouton modifier qui est visible, il n'y a que les boutons retour et annuler mon inscription, merci de m'aider

Hello

Please create a menu item to link to Registration History menu item type of Events Booking

Your registrants can then access to that menu item, see their registration history and update data from there
