  const link = document.createElement("a");
  link.style.display = "none";
  link.href = url;
  const fileName = new Date() + "-" + name + "." + suffix;
  link.setAttribute("download", fileName);
  document.body.appendChild(link);
  link.click();

        includes: ["index", "@timestamp", "message", ...this.selectedField],
