I have a public calendar to which everyone in the org has Show Detail access. When I add a new event to the calendar and set the “WhoId” equal to a Contact, the event does not show up on the Open Activities or Activity History list on the Contact Detail page. Is this the expected behavior?
Found this in the Salesforce Knowledge base.

Description Some customers would like for their Tasks/Events in their
Public Calendar to be linked to a specific record. Also for those

record level in the Open Activity related list

enter events they want to show up on the record level.
