gcp_cloudfunctions_cloud_function with function service account

New to Ansible and am attempting to write a playbook to add a Cloud Function to a GCP Project. This Cloud Function will run with its own Service Account ( https://cloud.google.com/sdk/gcloud/reference/functions/deploy ). The documentation for the Ansible module google.cloud

https://docs.ansible.com/ansible/latest/collections/google/cloud/gcp_cloudfunctions_cloud_function_module.html

doesn't mention anything about this. The only reference I've been able to find to this is

https://github.com/ansible/ansible/issues/62964

which was closed by the bot.

Where is the repo and issue tracker for google.cloud?

And, how do I specify the Service Account which the Cloud Function will use?

Jeff.
