Open only single instance of view

From my ShellViewModel I have below command binding to open another window "Remote View"

public ICommand RemoteViewCommand
         {
             get { return new RelayCommand(RemoteViewExecute, CanRemoteViewExecute); }
         }
 
  private void RemoteViewExecute()
     {
         if (!CanRemoteViewExecute())
         {
             return;
         }
 
         //call restore view
         //new ShellRemoteView().Show();
 
         ShellRemoteView shellRemoteView = Application._Container.Resolve<ShellRemoteView>();
         shellRemoteView.DataContext = Application._Container.Resolve<ShellRemoteViewModel>();
         shellRemoteView.Show();
     }
 

ie Every time I click button on shellView -> it opens as much instances of remote view.
How can I achieve only single instance of RemoteView to be opened/activate each time.
Any help would be really appreciated
