I don't believe any new Motorola phones have a notification light.
Your next best option might be to look at MotoDisplay alternatives like Notific. I recall it having an option where it would pulse your screen when you had notifications and battery performance didn't suffer too much.
Doesn't it have an ambient display mode? If not, won't take long before it does. My nexus 5 has it with a flashable mod.

I'm just casually checking out the Robin, but any phone that will run a notification app like Notific will provide a MotoDisplay-like feature that will notify you via the display. I've used it on my 2015 Moto E for a long time now.
I don't see anything wrong with an Allo web interface, but my point is these are obviously not a priority for any of these chat services for their primary use cases except for maybe Facebook.
Look into Notific if you want a "pulsing" visual notification alert. I like it better than Ambient Display, Moto Display, and AcDisplay.
Check out Notific. I like it better than Ambient Display, Moto Display, and AcDisplay.
Look into Notific as an alternative to MotoDisplay.
Notific is my favorite by far.
I used Notific on my M7, which did the trick. https://play.google.com/store/apps/details?id=com.anandbibek.notifyfree&hl=en
Give Notific a try. It's great.
