How to share a python program with specific users without python installed

Hi,
I have written a small chatbot using python. I would like to share the program with specific users in our organization. How can I achieve this?
when I take machine learning course by Andrew Ng. It looks they have published the Jupyter notebook as a web app and the web url is only accessible for registered users.

How is this done? Can someone give me some guidance?

If you want to host your app on the internet, you’ll need a site to host it.

There are DLAI courses that say how to do this. It isn’t simple.
