Accessing a Custom List view item 's bindings and passing it to another window through click event

I have a List view with Custom item container style which has two textblocks each binded to an property in the model used in the ViewModel's observableCollection

When i click an item i want it to show a new window containing more model properies based on the clicked item.

here is some of the code

// The model
public class Activity
{
   public string Title {get; set;} 
   public DateTime CreationDate {get; set;}
   public string MoreDetails {get; set;}
}

// The ViewModel
public class ViewModel
{
  public ObservableCollection<Activity> Activities {get; set;}

 public ViewModel
 {
 //Here i have pre added Activity objects to Activities 
 }
}

the ListView 's ItemsSource binded to Activities the first text block is binded to title and the second is to Date (in the Item style) sorry if this is a bit confusing i am new to WPF . im not on visual studio rn to show xaml

i have a second window which is supposed to show up with MoreDetails property binded in a textblock when an item is clicked How can i do that?
