Where did useUtils go?

    const utils = useUtils();
    const dataSource = useMemo(() => {
        return {
            getRows: async (params: any) => {

                utils.contacts.grid.fetch().then((response) => {
                    params.success({
                        rowData: response.rows,
                        rowCount: response.totalCount,
                    });
                });
                
            }
        }
    }, []);
