Hi @earthministry,
Sure, I will be happy to assist you in displaying your past events.
You can navigate to the “Display” tab and browse the “Event List Options” section. And check the “Show past events in the events list” section.
To enable the downloading of the event to the calendar you can browse further to the “Download to Calendar” section and check the “Add download button to the event” & “Add download button to event list” as per your requirement.
I have demonstrated the same in the video below.
