Hi,
I searched the web all over the place and withing Beaver builder itself but could not found what I wanted.
I want to use some jQuery libraries for my animations. How do I add other libraries into my project, so I can use those elements within my projects?
You could link the libraries to the site from a CDN, in the page head.
This is done in the theme customizer, not in Beaver Builder.
Add the library by using a <script> tag in Customizer > Code > Head.
With BB Theme: https://docs.wpbeaverbuilder.com/bb-theme/customizer-settings/code#head-code
