DLT doesn’t have a UI for library installation, but you can:

Use libraries configuration in the pipeline JSON or YAML spec:

{
  "libraries": [
    {
      "maven": {
        "coordinates": "com.sap.hana.hadoop:sap-hdlfs:<version>"
      }
    }
  ]
}

Or, if you’re using Python, add the dependency in your requirements.txt and reference it in the pipeline settings.
