How do I select a definite checkbox using the URL parameter?

My Code:

function Thumb(props) {

    const [selected, setSelected] = useState(null);
    const [loaderImg, setLoaderImg] = useState(false);
    const navigate = useNavigate();
    const itemId = useParams();

useEffect(() => {
        //setSelected({ itemId.id }) = checked;
        //console.log(setSelected);
    }, [itemId]);

function onChange(i) {
        setSelected((prev) => (i === prev ? null : i));
        selected ? navigate('/thumb') : navigate('/thumb/' + i); // localhost:3000/thumb or thumb/1 ...
    }

return (

        props.media?.map((item) => (
            <>
                <div
                    id={item.id}
                    key={uuidv4()}
                    className="thumb"
                    onClick={() => scrollTo(item.id)}
                >

                    <label>
                        <input
                            key={uuidv4()}
                            id={item.id}
                            type="checkbox"
                            className='thumb_check'
                            checked={item.id === selected}
                            onChange={() => onChange(item.id)}
                        />

                        {loaderImg ? null : (
                            <div className="loader">Lade ...</div>
                        )}

                        <img
                            style={loaderImg ? {} : { opacity: '0' }}
                            src={`../media/thumb_${item.id}.jpg`}
                            alt={item.id}
                            onLoad={() => setLoaderImg(true)}
                        />
                    </label>

                </div>

                {(item.id === selected && itemId.id !== item.id) ? // Show if Checkbox select and Param = item.id
                    <ShowImage>
                    : null}
            </>
        ))
    );
}

The Checkbox are only for Select only one Item in the multiple List.
I need a Script for activate the Checkbox (eg. 5) on write in the URL manuel localhost:3000/thumb/5

Thanks.
