You can conditional render the icon based on the value of the input field. Maintain a state for the value using the useState hook. onChange will trigger everytime you enter a value into the input field and set the state.

export default function Search() {
  const inputElt = useRef(null);
  const [value,setValue] = useState('')

  return (
    <form className='flex'>
     <input
        ref={inputElt}
        className='flex-grow focus:outline-none cursor-pointer'
        type='search'
        value={value}
        onChange={(e) =>setValue(e.target.value)}
    />
    {value && <XIcon className='h-5' />}
)
}
