Need Help With Vertical Slider JS Code


I’m having a hard time implementing a vertical slider that I found on this cloneable Webflow site I believe the code is sourced from here

I’m trying to customize it so that I can add an extra date to the slider. I believe the answer probably has to do with configuring the js that is being used in tandem with the design, but I’m not experienced enough with js to figure it out. If anyone has any extra tips for making it function better I’d appreciate that as well!

Thanks for helping.
