styled-components 적용 질문

AppLayout.propTypes = {

export default AppLayout;

제가 메뉴를 만들 때 ant 디자인 공식문서를 보고 const item에 요소를 작성해서 메뉴를 만드는 방식으로 코드를 작성했는데 이렇게 작서하니까 SearchInput에 styled 컴포넌트를 적용하는 것이 안됩니다 어떤 방식이 좋을까요?

const SearchInput = styled(Input.Search)`
  verticalalign: middle;
  width: 200px;
  marginleft: 10px;
`;

const items = [
  {
    label: <Link href="/">노드버드</Link>,
    key: "mail",
  },
  {
    label: (
      <div>
        <Link href="/profile">프로필</Link>
        <SearchInput
          placeholder="input search text"
          enterButton="Search"
          onSearch={onSearch}
        />
      </div>
    ),

맨위의 코드가 전체 코드이고 제가 궁금한 부분이 있는 코드는 아래에 있습니다
