H5 supports the new Google Identity Services
Last year, Google announced that there is a plan to deprecate the Sign-In JavaScript platform library. This will no longer be supported after March 31, 2023.
Beginning April 30, 2022, new applications must use the Google identity Service Library and existing apps may continue using the platform until the deprecation date.
In line with this, H5 Export to Google Sheets has now been migrated to use the new Google Identity Service.
Note: Google Sheets API key created previously should still be working.
