How do you navigate calendars in AppDaemon?

For now, I’m trying to see if a specific keyword is present in a specific calendar for each day of a given week.

I can get the calendar and attributes like any other entity, but I can’t really figure out how to get events/entries at specified dates or times. I can’t find anything about calendars in the docs (except a mention of a dashboard example from 2017).

Does anyone know how to interact with calendars in AppDaemon?
