Can't Delete Past Event or Edit Access

I can't find any way to delete a past event in Heartbeat. I also can't find a way to change access levels on past events. My use case was that I created some test events prior to launching my community & there was no way to get them off of the calendar (despite even removing the calendar integration). I'm not worrying about it for now because thankfully I had set the access to where no one will really see them, but it got me thinking this would be nice to be able to do.
