We've never been able to find such a capability with our existing Google Nest cameras and doorbells on our Google Nest Hubs. (We don't have a Max.) The only camera/doorbell notification I've been able to enable for the Hubs is a doorbell ring by turning on the "Visitor announcements" feature. (We do receive motion/person/package notifications on our phones.) Getting those notices on the Hubs would be a nice feature to have.
