How to use the @sentry/browser.Severity.Error function in @sentry/browser

confirm: null,
      message: 'modal.body_error',

    }));
    dispatch(historyPop());

  const { enabled, level, sampleRate } = appConfig.sentry;
  // Is not enabled
  if (!enabled) {
    return;

  const severityMap = {

    [Severity.Info]: SentrySeverity.Info,
    [Severity.Debug]: SentrySeverity.Debug,
  };

  let trackedSeverities = Object.getOwnPropertySymbols(severityMap).map(s => severityMap[s]);
  const minSeverityIndex = trackedSeverities.indexOf(level);
  if (minSeverityIndex > -1) {
    trackedSeverities = trackedSeverities.slice(0, minSeverityIndex + 1);
  }

  subscribe(appWillStart$, ({ getState }) => {
