Where to get driveAuthCode for 3DS config file?

Guide says "you will need to login to Google on your Switch" but there is no login page on 3DS.

3DS needs its own updated guide some time. They used to be identical, but when I saw switch will return the last url accessed, I changed to that method. I don't believe there's a way to do that for 3DS.

You have to go here: https://accounts.google.com/o/oauth2/v2/auth?client_id=YOUR_CLIENT_ID_HERE&redirect_uri=urn:ietf:wg:oauth:2.0:oob&response_type=code&scope=https://www.googleapis.com/auth/drive BUT you replace YOUR_CLIENT_ID_HERE with the client ID you have
