It should be trivial but I can't figure out how to have different title and subtitle in google search.

this is my metadata:

export const metadata = {
  title: "Thock",
  description: "Thock - The ultimate groupbuy tracker for mechanical keyboards.",
  icons: {
    icon: "/thock.svg",
  },
};

As you can see the description counts for both title and subtitle in search. How do I modify it?
