How to create an expandable ListView (SfListView) in .NET MAUI ?

<ListView:SfListView x:Name="listView" ItemsSource="{Binding ContactsInfo}"
                    AutoFitMode="DynamicHeight" SelectionMode="None" ItemSpacing="0,2.5,0,2.5">
    <ListView:SfListView.ItemTemplate>
        <DataTemplate>
            <Grid x:Name="grid" VerticalOptions="FillAndExpand" BackgroundColor="White" HorizontalOptions="FillAndExpand" RowSpacing="0">
                <Grid.RowDefinitions>
                    <RowDefinition Height="60" />
                    <RowDefinition Height ="*"/>
                </Grid.RowDefinitions>
                <Grid RowSpacing="0">
                    ...
                </Grid>
                
                <!--Expandable view-->
                <Grid x:Name="ExpandGrid" IsVisible="{Binding IsVisible}" ColumnSpacing="0" RowSpacing="0" Grid.Row="1" Padding="10,0,0,0"
                                        HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
                    ...
                </Grid>
            </Grid>
        </DataTemplate>
    </ListView:SfListView.ItemTemplate>
</ListView:SfListView>
