Unable to run "python -m example_scenes [Example] -pl"


I followed the video tutorial on this website here step by step:
[https://financial-engineering.medium.com/manim-how-to-install-manim-on-windows-10-f939f5418d79](url)
I may have installed the required files in different locations, but I tried linking them all to PATH under the Environment Variables settings.

The example doesn't show up in any video players and the cmd immediately moves on and asks for a new input.
I am completely new to Python, so I would not know just about everything. I downloaded Manim with the intention to animate Mathematics, but of course willing to learn Python along the way.

As of now, my current guess of how Manim would work is that I code somewhere on an app like Visual Studio, extract scenes and then run it in cmd?
I most definitely still need a lot of guidance on how to use it.

I also do not know what kind of info should I provide here in order to solve my issue. So it might be a thread that will go on for some time, but I would appreciate all the help I can get.

Thank you.
