How to use the @react-pdf/textkit/layout function in @react-pdf/textkit

import textDecoration from '@react-pdf/textkit/engines/textDecoration';
import scriptItemizer from '@react-pdf/textkit/engines/scriptItemizer';
import wordHyphenation from '@react-pdf/textkit/engines/wordHyphenation';

import fontSubstitution from './fontSubstitution';

const engines = {
  linebreaker,
  justification,
  textDecoration,
  scriptItemizer,
  wordHyphenation,
  fontSubstitution,
};

const engine = layoutEngine(engines);

export default engine;

import Font from '../font';
import transformText from '../text/transformText';
import isTextInstance from '../node/isTextInstance';
import fontSubstitution from '../text/fontSubstitution';

const engines = {
  linebreaker,
  justification,
  textDecoration,
  scriptItemizer,
  wordHyphenation,
  fontSubstitution,
};

const engine = layoutEngine(engines);

const layoutOptions = {
  hyphenationCallback: Font.getHyphenationCallback(),
  shrinkWhitespaceFactor: { before: -0.5, after: -0.5 },
};

const getFragments = instance => {
  if (!instance) return [{ string: '' }];

  const fragments = [];

  const {
    fill = 'black',
    fontFamily = 'Helvetica',
    fontWeight,
    fontStyle,
