How to use the @sentry/browser.init function in @sentry/browser

constructor() {
    if (process.env.NODE_ENV === 'production') {
      Sentry.init({
        dsn: process.env.SENTRY_DSN,

            console: true, // Log calls to `console.log`, `console.debug`, etc
            dom: true, // Log all click and keypress events
            fetch: true, // Log HTTP requests done with the Fetch API
            history: true, // Log calls to `history.pushState` and friends
            sentry: true, // Log whenever we send an event to the server
            xhr: true, // Log HTTP requests done with the XHR API
          }),
        ],
      });
    }
  }

function init(config) {
  // Only send events for errors which can be attributed to our code. This
  // reduces noise in Sentry caused by errors triggered by eg. script tags added
  // by browser extensions. The downside is that this may cause us to miss errors
  // which are caused by our code but, for any reason, cannot be attributed to
  // it. This logic assumes that all of our script bundles are served from
  // the same origin as the bundle which includes this module.
  //
  // If we can't determine the current script's origin, just disable the
  // whitelist and report all errors.
  const scriptOrigin = currentScriptOrigin();
  const whitelistUrls = scriptOrigin ? [scriptOrigin] : null;
