Проверка WhatsApp в последний раз

Я использую этот репо https://github.com/mgp25/Chat-API — У меня работает инструмент регистрации, но я хочу проверить, когда пользователь последний раз был в сети.

У меня в настоящее время есть этот код, который регистрирует меня, но, кажется, не проверяет статус людей — какие-нибудь идеи, как заставить это работать?
