The initialization of the Application Profile table array includes defining the callback function for Profile. It is `gattc_profile_event_handler()`. In addition, the GATT interface is initialized to the default value of `ESP_GATT_IF_NONE`. Later on, when the Application Profile is registered, the BLE stack returns a GATT interface instance to use with that Application Profile.
