How to enable multisorting for server side filtering?

  const table = useReactTable({
    data,
    state: { sorting: sortState, columnFilters: filters },
    manualSorting: true,
    enableMultiSort: true,
    manualFiltering: true,
    columns: tableColumns,
    getCoreRowModel: getCoreRowModel(),
    getExpandedRowModel: getExpandedRowModel(),
    onSortingChange: (sorting) => {
      if (onSort) {
        console.log(sorting()); // sorting() returns just on column, even if I hold down shift
        onSort(sorting());
      }
    },
    onColumnFiltersChange: (filterFn) => {
      if (onFilter) {
        onFilter(filterFn(filters));
      }
    },
    getRowCanExpand,
  });
