Google cloud run endpoint (extensible) service proxy api gateway firebase token - google-cloud-run

Question

Super basic (video) but the title is nearly my comment to Top 3 ways to run your containers on Google Cloud
User Authentication (content) in 2020 about api gateway from endpoints
Maybe a focal point for an answer could be the app engine role for api gateway in 2022. swagger.yaml (#comment)

I repeat attempts in seriatim:
gcloud api-gateway gateways delete backbank --location=us-central1
gcloud api-gateway api-configs delete backbank --api=backbank
gcloud api-gateway api-configs create backbank --api=backbank --openapi-spec=swagger.yaml --project=vaumoney --backend-auth-service-account=vaumoney#appspot.gserviceaccount.com
(a) gcloud endpoints services deploy swagger.yaml --project=vaumoney
(b) gcloud services enable vault-co.in (Principal-role permission name: "firebase-adminsdk")
gcloud run deploy backbank \
--image="gcr.io/vaumoney/endpoints-runtime-serverless:2.38.0-vault-co.in-2022-09-08r2" \
--set-env-vars ESPv2_ARGS=^++^--cors_preset=cors_with_regex++--cors_allow_origin_regex=^https:[/][/]i7l8qe.csb.app$++--cors_allow_methods=GET,POST,OPTIONS++--cors_allow_headers=Origin,Content-Type,Authorization,Referrer-Policy++--cors_allow_credentials \
--platform managed --project vaumoney
Of course, I incessantly get this:
The request was not authenticated. Either allow unauthenticated invocations or set the proper Authorization header. Read more at https://cloud.google.com/run/docs/securing/authenticating Additional troubleshooting documentation can be found at: https://cloud.google.com/run/docs/troubleshooting#unauthorized-client
But OPTIONS might be the problem (albeit "" on GET):
"This would be really useful for us, we're using cloud run for all our microservices and want to call these from a SPA via API Gateway." "We're back to Cloud Endpoints and ESPv2 for the time being, but we 100% see the benefits of the managed API Gateway, should CORS support be available for gRPC requests."
What am I to do?
