Why is anime.js not working?

Question

JavaScript

For animation I use anime.js
I took a regular primitive

<svg width="200" height="200" viewbox="-0.1 -0.1 4 4">
  <path id="path" d="M0,0  2,0  2,0  2,2  0,2z" fill="none" stroke="red" stroke-width="0.02"/>
</svg>

And then according to the instructions on onclick , the shape change animation should start ( the demo is attached with commented svg code ) but this thing does not work

Answer 1
