Incorrect on https://airflow.apache.org/docs/apache-airflow-providers-databricks/stable/operators/run_now.html
It's also incorrect in some places on https://airflow.apache.org/docs/apache-airflow-providers-databricks/stable/_api/airflow/providers/databricks/operators/databricks/index.html#airflow.providers.databricks.operators.databricks.DatabricksRunNowOperator, but I wasn't sure where to fix that.
