Can't use secondary Google drive

[paplorinc]

drive.mount(google_drive_mount_path) gives Error: credential propagation was unsuccessful if I select a different account than the one from google colab. The auth is successful, I even get an email Google Drive for desktop was granted access to your Google Account

I know you may not be able to fix this, I couldn't find a functioning workaround: googlecolab/colabtools#2732 (comment)

This is also unexpected for me, as I think the Google Drive authentication should be independent of the Google account that is used to run the Colab Notebook...

But if you're able to do so, this might be able to work around by using a different browser profile entirely to run the Colab Notebook also under the secondary Google account - as I've done this before.

Not the browser profile, the colab account, i.e. it seems I can only use the same drive that belongs to the Colab pro account

I got your point. Colab Pro subscription can't be shared so it's necessary to use your main Google account to run notebooks.

Maybe we can find a way to mount S3 buckets in Colab notebooks, I'm interested in this too.
