The Google Drive connector and Managed Translation are integrated to enable project creation with content selected straight from the Google Drive repository.
Retrieving projects from Managed Translation You can retrieve completed projects in two ways: download the files to your local computer or upload the files back to their original repository.
Shared Drives To work with Shared Drives, you need to have access to Google Drive Workspace, which is a paid service. An alternative would be to sign up for a 30-day free trial of Google Drive Essentials, which also has the Shared Drives capability.
