How to use the blessed.message function in blessed

let selected = infoList.selected;
  if (selected < OPTIONS.length) {
    let optionKey = OPTIONS[selected].split(',')[0].replace(/\W/g, '');
    helpText = yargsOptions[optionKey].describe;
    boxTitle = optionKey + ' option';
  } else {
    let replacementObj = REPLACEMENTS[Object.keys(REPLACEMENTS)[selected - OPTIONS.length]];
    helpText = replacementObj.description;
    boxTitle = replacementObj.name + ' Variable';
    if (replacementObj.parameters) {
      helpText += '\n\nParameters: ' + replacementObj.parameters.description;
    }
  }
  helpText += '\n\n{center}Press space to close{/center}';

  let msg = blessed.message({

    top: 'center',

  });
  msg.display(helpText, 0, function() { msg.destroy(); });
});
