3. Open link, but do not click on folder test2 and test3
4. Execute code below. Expected to see folders test1, test2 and test3. But only test1 is in output

Code example

        folders = drive.files().list(pageSize=10,
                                     q='mimeType = 'application/vnd.google-apps.folder'',
                                     fields="nextPageToken, files(id, name,  parents)").execute()
        nextPageToken = folders.get('nextPageToken')
        while nextPageToken:
            nextPage = drive.files().list(pageSize=10,
                                          driveId=drive_id,
                                          q='mimeType = 'application/vnd.google-apps.folder'',
                                          fields="nextPageToken, files(id, name,  parents)",
                                          pageToken=nextPageToken).execute()
            nextPageToken = nextPage.get('nextPageToken')
            folders['files'] = folders['files'] + nextPage['files']
        print(folders)

Note: if share folder with share button and adding email it output all the inner folders immediately.

If explanation is not clear I can record a video of it.
