Using Babel and Postcss to Webflow

Hello there, I’m pretty new in dev and would be more than happy to receive some help.

I’m creating my own website and would like to add a pencode script to webflow.
Here the pencode :

The thing is that I would like to change a bit the code in order to be interactive as it is on scroll on this website :
But still want it it to be interactive like it is on the pencode.

I tried to import this in a embed section but it’s not seems to working. Then I understand that I need to convert the babel script into a strict JS.
Done that as well through but still not working.

So I would be more than happy to get some help in order to understand what to do :slight_smile:

Hope that this topic is not unnecessary and unwanted here.
Have a great day or night and good coding between !
