Summary: Implementing export to excel and send to Google Drive feature. As part of this feature few things were implemented: - Server side google authentication exposed on url: (docs, docs-s, or localhost:8080)/auth/google - Exporting grist documents as an excel file (xlsx) - Storing exported grist document (in excel format) in Google Drive as a spreadsheet document. Server side google authentication requires one new environmental variables - GOOGLE_CLIENT_SECRET (required) used by authentication handler Test Plan: Browser tests for exporting to excel.
