How to import javascript classes into another javascript method?

Hi Frank,

good question! I so far didn´t succeed to use anything with "export" in my code.

Currently I use following two ways to embed external libs:

1. https://aras.com/en/blog/display-workflow-timeline-using-vis-js - See code sample

2. If the concept shown in this blog post code doesn´t work for whatever reason, I directly embed the class in the Form inside an html element. This works always. But I prefer the variant in the blog post, cause custom libs references in Methods are easier to see.
