   Note that the `GoogleDriveHook` inherits from the [GoogleBaseHook](https://airflow.apache.org/docs/apache-airflow-providers-google/stable/_modules/airflow/providers/google/common/hooks/base_google.html#GoogleBaseHook), which has the method `download_content_from_request`. You can use this method to write data to a file handle, e.g. a `BytesIO` object. You can then write the contents of that object to disk.
   
   Instead of adding functionality to the hook, you might want to consider creating a transfer operator, e.g. `gdrive_to_local.py` and leverage the existing functionality of `GoogleDriveHook`. You can use the `_upload_data` method in the [GoogleDriveToGCSOperator](https://github.com/RNHTTR/airflow/blob/f9d442f9a85b4b705bbe574f718034cf6bab5486/airflow/providers/google/cloud/transfers/gdrive_to_gcs.py) as an example, but instead of passing the value of the file handle to GCS, you can [write it to a file](https://stackoverflow.com/a/60450462/7004653).
