Bigquery authentication with service account

[crbl1122]

Hi! I am looking at the example provided for gcp_bigquery_client but I have an authentication issue. I am running the code from a Google Compunte Engine and I am using a service account to access resources (like BigQuery), not a credentials file. The example I see is only for credentials file usage. According to Google recommendation: "Service account keys could pose a security risk if compromised. We recommend you avoid downloading service account keys and instead use the Workload Identity Federation " but the examples given here are using files with service account keys.
Is there an example about how I can authenticate with this client into BigQuery using Google recommended method Workload Identity Federation? As for now I usually use an attached service account: username@project_id.iam.gserviceaccount.com whenever I access different resources, either from Compute Engine or pipelines like Kubeflow.
