For previewing only certain events, you can use an option to Filter Events using an icon next to the Calendar one.
In the filter, you can search for the Event by parameters:
- Unit (to search by the event it needs to be public and a user needs to have permissions to that Unit)
- Event statuses (Draft, Published, Cancelled)
- Events start date (the day of the event is happening, not its duration)
- And you have an option to include in the search the events of Subunits
