How to include mburger.js in mmenu

I try to include an animated hamburger in my mmenu. Documentation here: https://mmenujs.com/mburger/ I downloaded all the Files from gitHub, but I can not find where to include the mburger.js file. Can somebody help me? Thank you

I found it in the documentation:

• for css in "Tutorial CSS"
• for js in "Tutorial webcomponent"

Just read it!
