-          Enabling this will send all the ingested data to the "logs" data stream. This feature is disabled by default. If enabled the Dataset name option is ignored. "Write to logs streams" option must be enabled in the output settings for this to work.
+          When enabled, data ingested by this integration is written to the "logs" data stream, and the configured dataset name is ignored. You also need to enable **Allow agents to write to Streams** for the output policy in the Fleet **Settings** tab.
