Why is the snippet-bot complaining about the region tag prefix?

samples/snippets/async_api.py:15, tag cloudoptimization_async_api
samples/snippets/sync_api.py:15, tag cloudoptimization_sync_api

cloudoptimization_ is the correct prefix according to this page, no?

Hi @busunkim96 , I'm getting a permission denied error from sample checks:

Failed: google.api_core.exceptions.PermissionDenied: 403 Cloud Optimization API has not been used in project 1012616486416 before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/cloudoptimization.googleapis.com/overview?project=1012616486416 then retry.

I don't have access to the project and can't enable the API. Could you grant me the access or help me enable the API?

@changsongd I've enabled the API. Could you let me know what IAM permissions I should grant to the service account so it can run the samples?

Hi, you might need to add the role of Cloud Optimization AI Editor.

@changsongd Hmm I can't find that role in the dropdown (or in https://cloud.google.com/iam/docs/permissions-reference), are the roles fully rolled out?

The tests look like they're failing now because the requests include the unresolved env var names:

@dizcology suggested using the generated code samples in the documentation. I will close this PR. Thank you @busunkim96 for all your efforts and helps!
