How To Integrate Google Calendar?

I’m trying to make a game that upon booting up your assistant in the game will tell you about things on your phone’s Calendar. Is there a simple way to integrate Google Calendar into a Unity C# application? If not, can I see some example code with notes on what is doing what so I can actually learn? I have a basic idea and will update this post if I find it out myself.

I know this is from 2016, but for anyone new seeing this, maybe you can implement the Google Calendar API: Google Calendar  |  Google for Developers

I haven’t tried myself, but that’s my guess.

Have you found an answer for this ?
I’m trying to integrate some kind of exisiting calendar with event/appointment creation functionality within my app.
