ShareGate Migrate cannot list the files of a shared drive from Google Drive. To solve this problem, go to your Google Drive admin panel to add a member to your shared drive, then refresh your drive in ShareGate Migrate.
To learn how to add a member, see the Google article Manage shared drives as an admin.
Tip: If the refresh doesn't work, try to reconnect to Google Drive.
