Add email instead of notification to calendar event

eMC 9.2.2157 on Windows 11

When I create a new calendar entry, there’s a field for a notification. However, I can’t find anything for an email instead (or in addition to) the notification. On my Google calendar via their web interface I can add either or both.

How do I add an email to a calendar event in eMC? Also, is there a way to make it the default for new events?

Thanks.
