Custom Bugs that Walk Javascript to run on Twenty Nineteen Theme

Hello. We am trying everything we can find to get this custom javascript at https://auz.github.io/Bug/ to run on one our site pages. We are currently developing locally via the Twenty Nineteen child theme. Currently running through the very comprehensive list on https://plethorathemes.com/wordpress-tips-tutorials/how-to-add-javascript-or-jquery-to-wordpress/ Still nothing seems to be working. Obviously something specific that I’m doing wrong when none of the methods are working. I’m not extremely familiar with using or implementing custom Javascript within WordPress and this one appears to have a lot of files. Any direction anyone could point us would be most appreciated. It looks like we have to install the Javascript files and then initialize it to run. I’m not exactly sure where to put the initialization code. Would I be doing this via plug-in or enqueueing in the functions.php file? Would this be two separate things I have to set up? If I could at least get it to run site-wide first and then I can probably figure out how to get it to run on one page only. Thank you so much.
