+ * Update the connector features.
+ * Update the connector features in the connector document.
+ * This API can be used to control the following aspects of a connector:
+ *
+ * * document-level security
+ * * incremental syncs
+ * * advanced sync rules
+ * * basic sync rules
+ *
+ * Normally, the running connector service automatically manages these features.
+ * However, you can use this API to override the default behavior.
+ *
+ * To sync data using self-managed connectors, you need to deploy the Elastic connector service on your own infrastructure.
+ * This service runs automatically on Elastic Cloud for Elastic managed connectors.
