How to load balance Google Cloud Run for multi-region architecture

Question

I'm trying to create a multi-region Google Cloud Run setup and can't find any documentation.

My goal is creating an Google HTTPS Load Balancer and map the targets as my 3 Google Cloud Run instances.

https://lb.test.com/ > 

eu.test.com > Europe Cloud Run
na.test.com > North America Cloud Run
sa.test.com > South America Cloud Run

Problem is, I can't find the option of mapping my HTTPS load balancer into my Cloud Run instances.

If this is not possible yet, can I use an external DNS LB such as AWS Route 53?

Thanks!

Mapping load balancer to cloud run is possible now. This can be achieved by creating NEGs (Network Endpoint Groups) which points to a cloud run service.

I have implemented this today, and came across this thread. To find out how to implement this follow instructions in
