You're only using it wrong if you're trying to avoid triggering hooks as something other than a performance optimization.

For example, something like this should work correctly even without useCallback, but you would be constantly re-subscribing for no good reason.

    const callback = useCallback(...);

    useEffect(() => {
        const unsubscribe = subscribe(callback);
        return () => unsubscribe();
    }, [callback]);
