YouTube-загрузчик

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 нужную информацию, но не смог реализовать ее в приведенном выше коде.

Руководство по загрузке видео с YouTube V3 OAuth API на стороне сервера PHP

Русская информация и код "[Примеры] Авторизация (получение токена доступа и обновления) OAuth 2.0 с Google и работа с Google API в PHP"

Я могу получить токен обновления и сохранить все в файл или сеанс, но как интегрировать проверку и обновление токена в приведенный выше код?

Помогите мне, пожалуйста!
