How to use the contentful-migration/built/lib/migration-parser.default function in contentful-migration

const run = async ({
  spaceId, environmentId, accessToken, dryRun, migrationFunction
}) => {
  const config = { spaceId, environmentId, accessToken }
  const clientConfig = Object.assign({
    application: `contentful-migrate/${version}`
  }, config)
  const client = createManagementClient(clientConfig)

  const makeRequest = (requestConfig) => {
    // eslint-disable-next-line no-param-reassign
    requestConfig.url = path.join(config.spaceId, 'environments', environmentId, requestConfig.url)
    return client.rawRequest(requestConfig)
  }
  const migrationParser = migrationParser1.default(makeRequest, clientConfig)
  let parseResult
  try {
    parseResult = await migrationParser(migrationFunction)
  } catch (e) {
    if (e instanceof SpaceAccessError) {
      const message = [
        chalk.red.bold(`${e.message}\n`),
        chalk.red.bold('🚨  Migration unsuccessful')
      ].join('\n')
      console.log(message)
      process.exit(1)
    }
    console.log(e)
    process.exit(1)
  }
  if (parseResult.hasStepsValidationErrors()) {
