When Events is toggled on in App Permissions, it turns on an Events tab in the new client portal's left menu. I would think this would be tied to the Events that are scheduled within the Communities the user is registered in. However, this doesn't appear to be the case. In my membership community, I have a bunch of Events showing up in the Events tab within the community, but no events showing up at the portal level. I've just toggled off that tab for now. Is it a bug, or does it work differently than I'm assuming?
