WPF Static Status Bar Message Access

I am creating a WPF application and in the MainWindow.xaml code I have a status bar. I have a StatusBarMessage property which is bound to the status bar. I want this property to be static so that I can update the message in any of the view models. Does anyone have suggestion about the best solution for this?

Here is an example of how to bind to and raise change notifications for a static property:

public class StatusBarViewModel
{
    private static string _status;
    public static string Status
    {
        get => _status;
        set
        {
            _status = value;
            StaticPropertyChanged?.Invoke(null, new PropertyChangedEventArgs(nameof(Status)));
        }
    }

    public static event PropertyChangedEventHandler StaticPropertyChanged;
}

XAML:

 <TextBlock Text="{Binding Path=(local:StatusBarViewModel.Status)}"/>
