After some digging around, I found homebridge [0] (with the homebridge-unifi-protect plugin by hjdhjd [1]) which fixed that for me by tying the UI Protect system into Apple's HomeKit ecosystem (which also leverages the homekit secure video that keeps alerts/motion/snapshots on iCloud). Now all our devices are able to have it popup alerts for motions, packages, etc.
It's not perfect, but this way I'm able to get alerts without tying in to Unifi's SSO system. I also still like to open the UI Protect app when I'm not on the local network to sometimes archive videos, view cameras, mess with one of the new UI PTZ cameras, so I have backup access options, including Tailscale. Tailscale doesn't give me the alerts I want, but lets me access the app as if I were still at home. I also have it tied in with HomeAssistant and recently began playing around with go2rtc.
I'm a super-newb when it comes to all this but 2022 is when I began getting fed up with all these privacy nightmares and began to teach myself selfhosting, docker, etc so I can mitigate all this. Unfortunately, I'm the only one who knows how to tinker and keep all this updated. However, I do have documentation for my wife how to access everything and start fresh to make it easier on her by using UI's SSO way so it "just works" as they say in the Macintosh World, when I'm no longer around.
