(function (history, trackingId, options) {
    const getParameterByName = (paramName) => {
        var searchString = window.location.search.substring(1),
            i, val, params = searchString.split("&");
        for (i=0;i<params.length;i++) {
          val = params[i].split("=");
          if (val[0] == paramName) {
            return val[1] || undefined;
          }
        }
