'globalThis' is not defined?

Question

React

const Darko = () => {
  const history = useHistory();
  const [logout, { loading, error }] = useMutation(LOGOUT, {
    onCompleted: () => {
      history.push("/");
      globalThis.location.reload();
    },
    fetchPolicy: "no-cache",
  });
  return <div>...</div>}

Why am I getting the error 'globalThis' is not defined ?
