Im following the example Alert Notification Application and read this instruction:

In nRF Connect, create the Alert Notification Service (ANS) server by performing the following steps: In Server Setup, click the settings button and select "Load setup". In the resulting window, navigate to the \examples\ble_peripheral\ble_app_alert_notification folder. Load the file AlertNotifServer.ncs.
