ios — Codeigniter APN.where для помещения файла .pem в код php

Я работаю над проектом codeigniter, который требует отправки push-уведомлений на устройства ios.
При импорте библиотеки eapn я просто не могу понять, куда поместить файл .pem, который я экспортировал из проекта приложения ios.
а также я не могу понять, как ссылаться на его путь.

Вот библиотека Pushnotification.php
