gcloud resource-manager -- how to tag firebase hosting site?

[tonymet]

What are the correct values for --parent and --location for attaching tags to a Firebase Hosting Site?  The tags are needed to enforce IAM conditional restrictions

--tag-value=tagValues/281475861230371 , 
site = --parent=//firebasehosting.googleapis.com/projects/tonym-us/sites/dev-gcloud-go 

Full command and Error
