blazor Grid Grouping Expand/Collapse All

Hi,

I would like to have a Expand/Collapse All Grid Groups button in the Grid Header. I know this is possible to do so programmatically outside of the grid but my users want it inside the Grid.

Thanks,

Humayoon

Duplicated Items

using version 6.2
I have a button. If my items are already grouped, I can do the following:
```

private async Task ExpandCollapse()
{
    _isExpanded = !_isExpanded;
    var state = _grid.GetState();

    if (_isExpanded)
    {
        state.CollapsedGroups = null;
        state.ExpandedItems = _alerts;
    }
    else
    {
        state.CollapsedGroups = Enumerable.Range(0, _items.ToList().Count).ToList();
    }

    await _grid.SetStateAsync(state);

}
