Add slide numbers to Jupyter Notebook Slides

I would like to add slide numbers to a Jupyter Notebook slideshow. I found an issue about this, but I am not sure how and if it possible to add slide numbers to your slides in Jupyter Notebook slideshow. Here is some reproducible code to make a slide show:

# Jupyter Notebook Slides

I would like to add a slide number here?

Using the command in the terminal:

jupyter nbconvert test_slides.ipynb --to slides --post serve

So I was wondering if anyone knows how to add a page number to your slides in a Jupyter Notebook Slideshow?

As mentioned by @Wayne in the comments, you could use the following command:

jupyter nbconvert notebook_slides.ipynb --to slides --SlidesExporter.reveal_number='c/t'

Output:

As you can see it now has slide numbers!
