How to use the @sentry/node.Severity.Fatal function in @sentry/node

if (isAxiosError(originalError)) {
    code = `Request${originalError.code}`
  } else if (isJoiValidationError(originalError)) {
    code = 'JoiValidationError'
    info = originalError.details
  } else if (isSequelizeError(originalError)) {
    code = originalError.name
    if (isUniqueConstraintError(originalError)) {
      info = originalError.fields
      level = Severity.Warning
    }
  } else if (isApolloError(originalError)){
    level = originalError.level || Severity.Warning
  } else if (isError(originalError)) {
    code = _.get(originalError, 'code', originalError.name)
    level = Severity.Fatal
  }

  const formatError = {
    ...error,
    extensions: {
      ..._.get(error, 'extensions', {}),
      code,
      info
    }
  }
  Sentry.withScope(scope => {
    scope.setTag('code', code)
    scope.setLevel(level)
    scope.setExtras(formatError)
    Sentry.captureException(originalError || error)
  })
