This is a sample script for decoding a QR code put in Google Slides using Google Apps Script. In this case, Javascript is used at the opened dialog. And Canvas API and jsQR are used. So unfortunately, this method cannot be used with the time-driven trigger and the Google Apps Script project of the standalone type.

Of course, this method can be also used for Google Document and Google Spreadsheet. But at Google Spreadsheet, I recommend to retrieve the image of QR code with the fetch method from URL.
