I've managed to set up a cross-project backend for an External Regional Application Load Balancer, which works fine with Cloud Run. However, I'm looking to achieve the same configuration, especially with Cloud Functions and Buckets back-end service
The Global Load balancer setup accepts functions and buckets but it only allows backends within the same project, but I want to have cross-project backends for App Engine, Buckets, and Cloud Functions.
Has anyone successfully configured this type of Load Balancer setup? Any guidance or suggestions on how to achieve this would be greatly appreciated!
