Hi,
what have I done:

composer require 'drupal/juicebox:^4.0@alpha'
You need to install the jQuery Cycle plugin. If you have installed it check file paths. See the readme for more details.
Download the Library from https://juicebox.net/download/ and paste it inside your drupal
sites /libraries folder
2. Go inside /libraries/juicebox/web/jbcore and copy the juicebox.js file and classic
folder and paste it under /libraries/juicebox/
ok,correct done ... but

You need to install the "jQuery Cycle plugin" !! If you have installed it check file paths. See the readme for more details.

This is shown in drupal/views only format "slider"

I placed the  jQuery Cycle2.js here in Libaries:
juicebox
-classic
-jQuery Cycle2.js
-juicebox.js
no function with drupal 11 ?

Danke !
