How to use the @azure/ms-rest-js.URLBuilder.parse function in @azure/ms-rest-js

export function getURLQueries(url: string): { [key: string]: string } {
  let queryString = URLBuilder.parse(url).getQuery();
  if (!queryString) {
    return {};
  }

  queryString = queryString.trim();
  queryString = queryString.startsWith("?") ? queryString.substr(1) : queryString;

  let querySubStrings: string[] = queryString.split("&");
  querySubStrings = querySubStrings.filter((value: string) => {
    const indexOfEqual = value.indexOf("=");
    const lastIndexOfEqual = value.lastIndexOf("=");
    return (
      indexOfEqual > 0 && indexOfEqual === lastIndexOfEqual
    );
  });
