Thank you so much, it was exactly what I needed. For those who may receive error message, that app has not been verified, you should add your user as tester, then you will be given possibility to continue

Great video series!! A good thing to note here is that this flow is for desktop apps and won't work for web apps because they rely on a redirect URL to be specified.

When did you add the OAuth 2.0 credential for the desktop, or does it do it by default when you enable the api? In the video it looks like it was there already.
