When trying to use https://doc.ibexa.co/en/latest/administration/back_office/notifications/#notification-timeout is obtained the error Unrecognized option "success" under "ibexa.system.default.notifications". Available option is "subscriptions".

Looking closer, it seems that two bundles are in conflict, like https://github.com/ibexa/notifications/blob/main/src/bundle/DependencyInjection/Configuration/Parser/NotificationsConfigParser.php#L22-L24 is replacing https://github.com/ibexa/admin-ui/blob/main/src/bundle/DependencyInjection/Configuration/Parser/Notifications.php#L63
