How to delete item from ListView and ViewModel ObservableRangeCollection in Xamrin.Form?

I want to delete item from ListView and ViewModel ObservableRangeCollection in Xamrin.Form.

Here is my code. Please suggest.

EmployeeResultsPage

<ListView x:Name="EmployeeResultsListView"
          ItemsSource="{Binding EmployeeResults}"
          RowHeight="200"
          IsPullToRefreshEnabled="true"
          RefreshCommand="{Binding RefreshDataCommand}"
          IsRefreshing="{Binding IsRefreshingData, Mode=OneWay}"
          ItemAppearing="Employee_ItemAppearing"
    <ListView.ItemTemplate>
        <DataTemplate>
            <local:EmployeeResultViewCell />
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

EmployeeResultViewModel

[ImplementPropertyChanged]
public class EmployeeResultsViewModel : ViewModelBase
{
    private async Task LoadEmployee()
    {
        EmployeeResults = GetDataUsingAPI(); //15 records per call
    }

    public ObservableRangeCollection<ExtendedEmployee> EmployeeResults { get; set; }

    public string EmployeePhotoUrl { get; set; }
    public string EmployeeName { get; set; }
}

CS File

public partial class EmployeeResultViewCell : CustomViewCell
{
    public EmployeeResultViewCell()
    {
        InitializeComponent();
    }

    protected override void OnBindingContextChanged()
    {
        base.OnBindingContextChanged();
        var employee = (BindingContext as ExtendedEmployee);
    }
    private void MenuItemDelete_Clicked(object sender, System.EventArgs e)
    {
        //want to delete from list view
        //want to delete from ObservableRangeCollection<ExtendedEmployee> EmployeeResults defined in EmployeeResultViewModel
    }
}

EmployeeResultViewCell
I use <ViewCell.ContextActions> like MenuItem Text="Delete" IsDestructive="True" Clicked="MenuItemDelete_Clicked"

Please suggest.
