chanim VS Manim-Tutorial

I want to use manim to show the reaction mechanism as there is a tex package, chemfig, for drawing molecules. I found chanim, which solves my problem at some level, but its documentation is not rich enough. I properly use it to create ChemObject but couldn't show a reaction. There exist a Reaction class but I didn't understand how to use it correctly. Even create an issue https://github.com/raghavg123/chanim/issues/12. It will be a great help if anyone helps me to figure out how to use that class or solve that issue.

I use a LaTeX package called chemfig. Since it's a bit tedious to use basic Tex mobjects for this purpose, I created a few subclasses of my own specifically for chemistry (see: chanim)

I followed two guides, one is https://github.com/malhotra5/Manim-Tutorial and a youtube series by theorem of Beethoven, both of which suggested downloading the zip file and doing pip install requirements.txt

1/ register 2/ paste a piece of code from https://github.com/malhotra5/Manim-Tutorial 3/ rename the class to 'Demo' 4/ hit 'ctrl enter' 5/ your animation should show on the left side 6/ you can view all your past anims in the 'submissions' section
