GDrive requires several steps to configure.

You will start at the API credentials manager:\\
[https://console.developers.google.com/projectselector/apis/credentials]\\
\\
You first need to make a project.  My example calls this CrushFTP-Test.\\

Next select create credentials, and choose the Web Application type.\\

\\
It will warn you if you don't have an "OAuth Consent" screen configured, so go there and configure that screen too.\\
