I'm developing custom widgets for WAB (Develper Edtion) 2.20, Launchpad Theme, on 3D Scenes (ArcGIS API for javascript 4.20). I am still a newbie.
I want to use the "popmotion" library for animations, but I do not know how to "include" it the right way...
I saw in eseri article Feature selection styles in web scenes: the defaults and beyond
towards the end of "Style 3 - Display the bounding box of the feature" it is written:
On a final note, have a look at the animations that our colleague Hugo added to the bounding box: https://codepen.io/ralucanicola/pen/XWRXjOm.
and this example uses "popmotion" animation and runs ok in code-pen,
but When I copied what I see in code-pen into html page, it turned out that "popmotion" lib is not included and I get error.
I attach here a zip of my index.html file
I will appreciate help in how to include the "popmotion" lib, so the html page will run ok.
