how to extract the desktop notifications from already opened firefox browser with google colab opened

Question

I want to extract notifications that whether my colab cell has finished execution successfully or not, so I want to extract those messages, but not by opening  a new browser, web driver opens a whole new window, I am unable to find the code anywhere, everywhere it is shown to create notifications and not read them. I don't need to create , I just need to read the incoming colab notifications in python.
