+/**
+ * @brief Class used to subscribe to attributes and events from the remote bridged device.
+ *
+ * The Descriptor Cluster contains attributes such as the Parts List, which provides a list
+ * of endpoints or devices that are part of a composite device or bridge. The CommissionerControl
+ * Cluster generates events related to commissioning requests, which can be monitored to track
+ * device commissioning status.
+ *
+ * When subscribing to attributes and events of a bridged device from another fabric, the class:
+ *    - Establishes a secure session with the device (if needed) via CASE (Chip over
+ *      Authenticated Session Establishment) session.
+ *    - Subscribes to the specified attributes in the Descriptor Cluster (e.g., Parts List) and
+ *      events in the CommissionerControl Cluster (e.g., CommissioningRequestResult) of the remote
+ *      device on the specified node and endpoint.
+ *    - Invokes the provided callback upon successful or unsuccessful subscription, allowing
+ *      further handling of data or errors.
+ *
+ * This class also implements the necessary callbacks to handle attribute data reports, event data,
+ * errors, and session establishment procedures.
