QWC currently has the Qlik Google Drive & Spreadsheets Connector supporting
spreadsheets in Google Drive using the Google Sheets API.
But this is limited to private Google Drive accounts, can't update shared company Google Drives using this.
For that the connector would need to use the Google Drive API:
https://developers.google.com/drive/api/v3/enable-shareddrives
Dealing with company customers it is natural they wanting to use a shared company Google Drive.
Please updated the QWC Qlik Google Drive & Spreadsheets Connector with shared Google Drive support as soon as possible.
