How to use the @inquirer/core/lib/key.isUpKey function in @inquirer/core

useKeypress(key => {
    if (isEnterKey(key)) {
      setStatus('done');
      done(choices[cursorPosition].value);
    } else if (isUpKey(key) || isDownKey(key)) {
      let newCursorPosition = cursorPosition;
      const offset = isUpKey(key) ? -1 : 1;
      let selectedOption;

      while (!selectedOption || selectedOption.disabled) {
        newCursorPosition =
          (newCursorPosition + offset + choices.length) % choices.length;
        selectedOption = choices[newCursorPosition];
      }

      setCursorPos(newCursorPosition);
    } else if (isNumberKey(key)) {
      // Adjust index to start at 1
      const newCursorPosition = Number(key.name) - 1;

      // Abort if the choice doesn't exists or if disabled
      if (!choices[newCursorPosition] || choices[newCursorPosition].disabled) {
        return;

onKeypress: (value, key, { cursorPosition = 0, choices }, setState) => {
      let newCursorPosition = cursorPosition;
      if (isUpKey(key) || isDownKey(key)) {
        const offset = isUpKey(key) ? -1 : 1;
        let selectedOption;

        while (!selectedOption || selectedOption.disabled) {
          newCursorPosition =
            (newCursorPosition + offset + choices.length) % choices.length;
          selectedOption = choices[newCursorPosition];
        }

        setState({ cursorPosition: newCursorPosition });
      } else if (isSpaceKey(key)) {
        setState({
          showHelpTip: false,
          choices: choices.map((choice, i) => {
            if (i === cursorPosition) {
              return Object.assign({}, choice, { checked: !choice.checked });
            }
