how to create a load balancer for app engine and cloud run

Question

I currently have two services that do the same thing but in a different way, one is in the app engine and the other in cloud run and I need to create a load balancer in which the load can be shared by a single endpoint.

example

100 requests arrive and the balancer instructs it to make 50 requests to the app engine and the remaining 50 to cloud run.

You can use one serverless NEG per service (1 for cloud run, 1 for App Engine) and use URL Map to route the query to the corresponding NEG
