/**
 * Session store is a shared realtime key-value store that is accessible by all Peers in a Room.
 * It can be utilized to implement features such as pinned text, spotlight (which brings a particular
 * peer to the center stage for everyone in the room) and more, enhancing interactive experiences.
 *
 * To get an instance of `HMSSessionStore` class, You can add an event listener for `ON_SESSION_STORE_AVAILABLE`
 * event on the `HMSSDK` instance
 *
 * For example:
 * ```
 * hmsInstance.addEventListener(HMSUpdateListenerActions.ON_SESSION_STORE_AVAILABLE, <your callback function>);
 * ```
 *
 * Checkout Session Store docs fore more details ${@link https://www.100ms.live/docs/react-native/v2/how-to-guides/interact-with-room/room/session-store}
