BackgroundWorker open new window and update it - wpf

Question

I have a WPF utility tool that has a lot of processing to do. The processing is done from MainWindow.xaml which utilizes a BackgroundWorker to execute. What I want to do is open a new separate window called Logger.xaml and update a TextBox found on the Logger.xaml window on the progress of MainWindow's execution. The purpose of this is so that a user can continue to select more processing to do from MainWindow.xaml while still getting progress updates of ongoing work. So in layman's terms: 1 MainWindow to multiple Logger windows. Here is what I have so far.
MainWindow.xaml.cs:
private void btn_Click(object sender, RoutedEventArgs e)
{
bw = new BackgroundWorker();
bw.WorkerReportsProgress = true;
bw.DoWork += (a, b) => WorkerMethod(x, y); //WorkerMethod does all the heavy lifting
bw.RunWorkerAsync();
}
private void WorkerMethod(string x, string y)
{
/***some work 1 code***/
//Somehow open `Logger.xaml` and update its textbox that some work 1 finished.
/***some work 2 code***/
//Update its textbox that Work 2 finished.
etc...
}
Should I use BackgroundWorker.ProgressChanged somehow to open up a new Logger window on another thread and update the TextBox in that window? What is the best way to achieve the desired effect?

Yes, BackgroundWorker raises ProgressChanged events on the current SynchronizationContext of the thread that called RunWorkerAsync()..
To receive notifications of progress updates, handle the ProgressChanged event. To receive a notification when the operation is completed, handle the RunWorkerCompleted event.

If you want to use a BackgroundWorker, probably this is the best.
