How to detect a click outside a React component

import React, { useEffect, useRef } from 'react';
import { FiSearch } from 'react-icons/fi';
import { useDispatch, useSelector } from 'react-redux';
import { focusToggle } from '../Redux/actionsCreators/searchAction';

const SearchAutoComplete = () => {
    const state = useSelector((state) => state.searchReducer);
    const dispatch = useDispatch();

    const { suggestions, isFocus } = state;

    console.log(isFocus);

    const ref = useRef(null);
    useEffect(() => {
        const handleClickOutside = (event) => {
            if (ref.current && !ref.current.contains(event.target)) {
                dispatch(focusToggle(false));
            }
        };
        document.addEventListener('click', handleClickOutside, true);
        return () => {
            document.removeEventListener('click', handleClickOutside, true);
        };
    }, [dispatch]);

    return (
