I am trying to use `tinysoap` library (https://github.com/mhzed/tinysoap) in an Web AppBuilder Custom Widget.
I am able to use this library in WebAppBuilder application, as I show on the following sample code (real code included in HTML file). All my functions are included in a class called `myClass` in `customLibrary.js` file. Most functions in `customLibrary.js` call `tinysoap` functions, and everything works well:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="node_modules/tinysoap/tinysoap-browser-min.js"></script>
<script src="node_modules/lib/customLibrary.js"></script>
<script src="https://js.arcgis.com/4.15/
