Confirm application default credentials are an authorized user (env var GOOGLE_APPLICATION_CREDENTIALS is not set, and gcloud auth application-default login has been run and quota project has been added to ADC)\r\n  2. Run the code from the guide \"Querying Drive Data\"\r\n  ```\r\n from google.cloud import bigquery\r\nimport google.auth\r\n\r\n# Create credentials with Drive \u0026 BigQuery API scopes.\r\n# Both APIs must be enabled for your project before running this code.\r\ncredentials, project = google.auth.default(\r\n    scopes=[\r\n        \"https://www.googleapis.com/auth/drive\",\r\n        \"https://www.googleapis.com/auth/bigquery\",\r\n    ]\r\n)\r\n\r\n# Construct a BigQuery client object.\r\nclient = bigquery.Client(credentials=credentials, project=project)\r\n  ```\r\n3. Inspect the credentials and client variables. Neither will contain the drive scope provided.\r\nOR\r\n3.
