Can you be little more specific? What kind of application you build? What GAP and GATT roles exactly? Or are you referring to some Apple Homekit specific feature? If you are wondering about standard BLE GATT Notification method on top of some GATT Characteristic's Value hanlde then it is used in basically all GATT Server examples oin nRF5 SDK...
