¿Hay una manera de redirigir a un usuario a un navegador web cuando el usuario hace clic en el tostado de Windows generado en Python?

Antecedentes

estoy usando win10 Toast para importar la Biblioteca toastnotifier para empujar notificaciones Toast. Lo que quiero hacer es redirigir la notificación tostada a una página web cuando el usuario haga clic en ella (Windows 10).
Por ejemplo:
toaster.show_toast(subject,message,duration=20000,icon_path='C:/Users/kuni8004/Desktop/b.ico',**link ='www.stackoverflow.com'**)

acabo de hacer una versión que podría encajar con sus necesidades, y todavía estoy esperando a que se fusione con el repositorio original. El enlace es here
Sin embargo, si desea agregarlo manualmente, aquí está init. Lo que usted puede estar buscando es:
from __future__ import absolute_import
from __future__ import print_function
