I am pushing TabbedPage to MasterDetailPage from ViewModel by default TabbedPage showing first tab selected. How can select second tab?

This is my code in ViewModel

async Task MoviesTab()

 await (App.Current.MainPage as MasterDetailPage).Detail.Navigation.PushAsync(new HomePage());
 (App.Current.MainPage as MasterDetailPage).IsPresented = false;
 //var pages=new HomePage().Children.GetEnumerator();
 //pages.MoveNext();
 //new HomePage().TabIndex = 1; //Not working

HomePage has two tab defined in xaml

public partial class HomePage : TabbedPage

When ever calling MoviesTab() method from side menu always appearing first tab selected.

Edit

The first scenario is not working & second throwing NullReferenceExeption exeption

Scenario 1

var tabbedPaged = new TabbedPage();
tabbedPaged.TabIndex = 1;
await (App.Current.MainPage as MasterDetailPage).Detail.Navigation.PushAsync(new HomePage());
(App.Current.MainPage as MasterDetailPage).IsPresented = false;

Scenario 2

await (App.Current.MainPage as MasterDetailPage).Detail.Navigation.PushAsync(new HomePage());
(App.Current.MainPage as MasterDetailPage).IsPresented = false;
((App.Current.MainPage as MasterDetailPage).Detail as TabbedPage).TabIndex = 1;

Save the TabbedPage to a local variable and change the tab index before showing it:

var tabbedPaged = new TabbedPage();
tabbedPaged.TabIndex = 1;
await (App.Current.MainPage as MasterDetailPage).Detail.Navigation.PushAsync(tabbedPaged);

Or get the current Detail page after you have pushed it as the current Detail, cast it as a TabbedPage and then set the index:

((App.Current.MainPage as MasterDetailPage).Detail as TabbedPage).TabIndex = 1;
