let isScriptLoaded = false;
export const useElfsightScript = () => {
    useEffect(() => {
        if (typeof window === 'undefined')
            return;
        if (isScriptLoaded || document.getElementById('elfsight'))

        const onIdle = () => {
            const script = document.createElement('script');
            script.id = 'elfsight';
            script.src = 'https://static.elfsight.com/platform/platform.js';
            script.defer = true;

            document.body.appendChild(script);
            isScriptLoaded = true;
        };
        if ('requestIdleCallback' in window) {
