When we receive a notice for scheduled maintenance, it would be convenient if you give us a link or an ICS file to save them to the calendar. Ideally attached within the email, but also good to show them on the dashboard.

Since I belong to many teams, projects and databases, I received a lot of emails for the maintenance for datastores and disks at different times.

It's pretty straightforward to generate a Google Calendar URL or to generate an ICS file.
