Python SDK oauth_client list missing scope details in response

Running api.oauth_client_api.get_oauth_client() on our staging org. The response object comes back with the client ID and name, but the scopes field is completely empty. I need to audit which clients have oauth:client:manage assigned. Is there a separate endpoint to pull the granular scope mappings, or is this a bug in the Python SDK wrapper? The raw JSON payload just shows "scopes": [].
