Как добавить файл refresh_token, чтобы предотвратить сброс авторизации.

{"access_token":"ya29.GluQBs6GFi_0sG1VgmLUZ0....","expires_in":3600,"refresh_token":"1\/cLxr6ox0...","scope":"https:\/\/www.googleapis.com\/auth\/userinfo.email https:\/\/www.googleapis.com\/auth\/userinfo.profile","token_type":"Bearer","id_token":"eyJhbGc..","created":1547330141}

Я нашел информацию, но не смог реализовать ее в вышеприведенном коде.

PHP серверная Сторона YouTube V3 OAUTH API руководство по загрузке видео

[примеры] авторизация (получение маркера доступа и обновления) oauth 2.0 с Google и работа с Google API на PHP

Я могу получить маркер обновления и сохранить все в файл или session, но как я могу интегрировать проверку и обновление маркера в код выше?

Помогите пожалуйста!
