const onCheck = useCallback((newChecked) => {
setChecked((prevChecked) => {
// If newChecked is empty, just return an empty array
if (newChecked.length === 0) {
return [];
}

  // Keep only the last selected item
  const latestChecked = [newChecked[newChecked.length - 1]];

  // If the latestChecked is the same as the previously selected item, deselect it
  return prevChecked[0] === latestChecked[0] ? [] : latestChecked;
});

}, []);
