How to apply the background color when mouse hover on SfDataGrid in .NET MAUI?

The .NET MAUI DataGrid allows you to change the background color of the DataGrid when hovering over a cell on WinUI and MacOS platforms.

    public class DataGridBehavior : Behavior<ContentPage>
    {
        private SfDataGrid? dataGrid;
        private EmployeeViewModel? employeeViewModel;

        protected override void OnAttachedTo(ContentPage page)
        {
            base.OnAttachedTo(page);
            employeeViewModel = new EmployeeViewModel();
            dataGrid = page.FindByName<SfDataGrid>("dataGrid");
            dataGrid.ItemsSource = employeeViewModel.Employees;
#if WINDOWS || MACCATALYST
            dataGrid.CellHovered += DataGrid_CellHovered;
            dataGrid.CellExited += DataGrid_CellExited;
#endif
        }

#if WINDOWS || MACCATALYST
        private void DataGrid_CellExited(object? sender, DataGridCellExitedEventArgs e)
        {
            if(this.dataGrid != null && this.dataGrid.BackgroundColor != Colors.Transparent)
            {
                this.dataGrid.BackgroundColor = Colors.Transparent;
            } 
        }

        private void DataGrid_CellHovered(object? sender, DataGridCellHoveredEventArgs e)
        {
            if (this.dataGrid != null && this.dataGrid.BackgroundColor == Colors.Transparent)
            {
                this.dataGrid.BackgroundColor = Colors.Red;
            }
        }
#endif

        protected override void OnDetachingFrom(ContentPage page)
        {
            base.OnDetachingFrom(page);

#if WINDOWS || MACCATALYST
            if (dataGrid != null)
            {
                dataGrid!.CellHovered -= DataGrid_CellHovered;
                dataGrid.CellExited -= DataGrid_CellExited;
