You can use hook like this to check it's first mount/render

const useDidMountEffect = (func, deps) => {
    const didMount = useRef(false);

    useEffect(() => {
        if (didMount.current) func();
        else didMount.current = true;
    }, deps);
}

Next you can check result ot useDidMountEffect
