How to use it

To use this feature, configure the DeltaLake table engine to authenticate using AWS session tokens or environment credentials by setting the appropriate AWS environment variables or passing session tokens as part of the configuration. This allows ClickHouse to access DeltaLake tables with temporary or environment-provided AWS credentials.
