const wait = () => new Promise((resolve) => setTimeout(resolve, 1000));

export default () => {
  const [open, setOpen] = React.useState(false);

  return (
    <AlertDialog.Root open={open} onOpenChange={setOpen}>
      <AlertDialog.Trigger>Open</AlertDialog.Trigger>
      <AlertDialog.Portal>
        <AlertDialog.Overlay />
