 Because of the [CORS](https://github.com/zboris12/zgapdfsigner/wiki/API#note) security restrictions in web browser,
 signing with a timestamp from [TSA](https://github.com/zboris12/zgapdfsigner/wiki/API#note) or enabling [LTV](https://github.com/zboris12/zgapdfsigner/wiki/API#note) can only be used in [Google Apps Script](https://developers.google.com/apps-script) or [nodejs](https://nodejs.org/).
