How to view PyDrive2 files in Google Drive or Google Cloud Platform?

This is a really simple question. Not really a GitHub issue, but I have no idea where else to ask it.

I installed PyDrive2, created a project, created a service account, granted permissions, downloaded the permissions.json file, and cobbled together a basic Python script to store files on the account via PyDrive2. So far, so good.

The only problem is that I cannot, for the life of me, figure out how to view documents uploaded through PyDrive2 in either Google Drive or Google Cloud Platform. Things that I tried without success:

* The files do not appear anywhere in the Google Drive volume that is associated with my GCP account.
* Google Drive won't separately allow me to login separately as the service account.
* The Google Cloud Platform console has a wide variety of storage options - buckets, cloud volumes, etc. - but no option for an interface to Google Drive.

So, as it stands, I can't view PyDrive2-uploaded documents through any kind of file UI. It's like they just disappear into the cloud and are accessible only through PyDrive2.

Any suggestions?
