-### Debugging
-
-The SDK supports debug logging, which can be enabled for troubleshooting
-and debugging purposes. You can enable debug logging by setting the `debug`
-flag to `true` when initializing the `Zitadel` client, like this:
-
-```python
-zitadel = zitadel.Zitadel("your-zitadel-base-url", 'your-valid-token', lambda config: config.debug = True)
