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

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 });
            }

            return choice;
          })
        });
      } else if (key.name === 'a') {
        const selectAll = Boolean(choices.find(choice => !choice.checked));
        setState({
          choices: choices.map(choice =>
            Object.assign({}, choice, { checked: selectAll })
          )
