Declaration of en_text_rec in NRF52 NFC Record text Example

[Ramkumar]

    static void en_record_add(nfc_ndef_msg_desc_t * p_ndef_msg_desc)
{
    /** @snippet [NFC text usage_1] */
    uint32_t             err_code;
    static const uint8_t en_payload[] =
                  {'H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd', '!'};
    static const uint8_t en_code[] = {'e', 'n'};

    NFC_NDEF_TEXT_RECORD_DESC_DEF(en_text_rec,
                                  UTF_8,
                                  en_code,
                                  sizeof(en_code),
                                  en_payload,
                                  sizeof(en_payload));
   /** @snippet [NFC text usage_1] */

    err_code = nfc_ndef_msg_record_add(p_ndef_msg_desc,
                                       &NFC_NDEF_TEXT_RECORD_DESC(en_text_rec));
    APP_ERROR_CHECK(err_code);

}

In this above example, where can i find the declaration of the en_text_rec ?? I want to add a text message record to the launch app record NFC example for the NRF52.
