+ * Hook which synchronously executes a callback once the component has been mounted.
+ *
+ * `WARNING` This should only be used if you need to perform an action after the component has been mounted and
+ * before the browser paints. useMountSync will trigger debug warnings in server-rendered scenarios and should be used
+ * sparingly.
+ *
+ * @deprecated Consider to use React.useEffect() or React.useLayoutEffect() directly based on a use case
+ *
+ * @param callback - Function to call once the component has been mounted.
