ADDING Extra "notification attributes" IN ANCS

Question

Hi, team I am using nRF5_SDK_15.3.0_59ac345/examples/ble_peripheral/ble_app_ancs_c sample application. and i wnated to add extra notification attribute. added BLE_ANCS_KEY1 in this Enum ble_ancs_c_notif_attr_id_val_t. /**@brief IDs for iOS notification attributes. */ typedef enum { BLE_ANCS_NOTIF_ATTR_ID_APP_IDENTIFIER = 0, /**< Identifies that the attribute data is of an "App Identifier" type. */ BLE_ANCS_NOTIF_ATTR_ID_TITLE, /**< Identifies that the attribute data is a "Title". */ BLE_ANCS_NOTIF_ATTR_ID_SUBTITLE, /**< Identifies that the attribute data is a "Subtitle". */ BLE_ANCS_NOTIF_ATTR_ID_MESSAGE, /**< Identifies that the attribute data is a "Message". */ BLE_ANCS_NOTIF_ATTR_ID_MESSAGE_SIZE, /**< Identifies that the attribute data is a "Message Size". */ BLE_ANCS_NOTIF_ATTR_ID_DATE, /**< Identifies that the attribute data is a "Date". */ BLE_ANCS_NOTIF_ATTR_ID_POSITIVE_ACTION_LABEL, /**< The notification has a "Positive action" that can be executed associated with it. */ BLE_ANCS_NOTIF_ATTR_ID_NEGATIVE_ACTION_LABEL, /**< The notification has a "Negative action" that can be executed associated with it. */ BLE_ANCS_KEY1, } ble_ancs_c_notif_attr_id_val_t; and also added "KEY1" to lit_attrid /**@brief String literals for the iOS notification attribute types. Used when printing to UART. */ static char const * lit_attrid[BLE_ANCS_NB_OF_NOTIF_ATTR] = { "App Identifier", "Title", "Subtitle", "Message", "Message Size", "Date", "Positive Action Label", "Negative Action Label" "KEY1" }; and added in service_init function ret = nrf_ble_ancs_c_attr_add(&m_ancs_c, BLE_ANCS_KEY1, m_attr_negaction, ATTR_DATA_SIZE); APP_ERROR_CHECK(ret); And I am sending push pay load { "aps" : { "alert" : { "body" : "Body" , "title" : "title" , "subtitle" : "New Subtitle" , "key1" : "Value1" } } } from the following site https://pushtry.com and following printed in the serial monitor app: App Identifier: com.xcubelabs.demo app: Title: title app: Subtitle: New Subtitle app: Message: Body app: Message Size: 4 app: Date: 20200113T app: Positive Action Label: (N/A) app: Negative Action LabelKEY1: Clear app: : (N/A) But i didnt get that key value. please help me out this problem. if any Example code snippets are availble please send to me .
