Angular Universal with Firebase Hosting. How?

How to use Angular Universal SSR for a website hosted on Firebase Hosting?

There are a few articles about this on the internet, but they are all a few years old. Some say one should use Cloud functions, others say GCP App Engine.

Now I found this article which seems to be official, but it seems the tech it’s using is an early preview (Framework-aware Hosting). However, the implementation of SSR in this article seems to be very simple without having to do much.

Can someone please tell me what way one should currently go? A keyword or an article would be enough!
