This section allows an administrator to define which projects' Jira events will trigger updates to real-time update Google Sheets. By default, every project is enabled. Administrators may find that some projects do not need to update Google Sheets, and disabling those projects here may provide a performance benefit. Jira events fired from issues in projects that are not enabled here, will be ignored. Note that this section and the 430932007 Webhooks section work together; the add-on will only process enabled events on realtime-enabled projects. Users are still able to export issues from projects that are not enabled here, but changes to issues in those projects will not trigger real-time updates, even if the sheet itself is realtime-enabled.
