Describe the bug and the steps to reproduce it

I am trying to load the subRows from the server when the user clicks on the expand button but this function does not get called no matter how its used.

Minimal, Reproducible Example - (Optional, but Recommended)

import React, { useMemo } from 'react';
import { MantineReactTable, useMantineReactTable } from 'mantine-react-table';
import { MantineProvider } from '@mantine/core';

//simple data example - Check out https://www.mantine-react-table.com/docs/examples/remote for a more complex example
const data = [
  {
    name: 'John',
    age: 30,
  },
  {
    name: 'Sara',
    age: 25,
  },
];

export default function App() {
  const columns = useMemo(
    () => [
      {
        accessorKey: 'name', //simple recommended way to define a column
        header: 'Name',
        muiTableHeadCellProps: { sx: { color: 'green' } }, //custom props
        Cell: ({ renderedCellValue }) => {
          return <strong>{renderedCellValue}</strong>;
        },
      },
      {
        accessorFn: (row: any) => row.age, //alternate way
        id: 'age', //id required if you use accessorFn instead of accessorKey
        header: 'Age',
        Header: <i style={{ color: 'red' }}>Age</i>, //optional custom markup
      },
    ],
    []
  );

  const table = useMantineReactTable({
    columns,
    data,
    manualExpanding: true,
    enableExpanding: true,
    enableExpandAll: false,
    paginateExpandedRows: false,
    filterFromLeafRows: false,
    expandRowsFn: (dataRow) => {
      console.log(dataRow);
      return dataRow.subRows;
    },
    getRowCanExpand: (row) => {
      return true;
    },
  });

  return (
    <MantineProvider
      theme={{
        colorScheme: 'light',
        primaryColor: 'blue',
      }}
    >
      <MantineReactTable table={table} />
    </MantineProvider>
  );
}

I could use onExpandedChange instead.
