Angular Universal: The requested URL was not found on this server.

[MawRojas]

Hello. First of all, I'd like to say thank you for this feature. I'm pretty excited to use it.
The issue I'm facing is the following: accessing any route that is not the root by either using the address bar or reloading the page throws a 404 error.
After doing some dinning, I found it this problem is well documented here and here. However, both of those solutions seem to apply for apache servers only.
In both solutions, they pretty much force the server to always render index.html regardless of the route.
How can I implement something like that for firebase hosting?
