updating from 2.3.6 to 3.2 it is possible?

so I have a working app with AdminLTE 2.36, I want to update to 3.2 version to fix some issues on some browsers.

First I install the new version and I get:

PS C:\Manuel\argus> npm install admin-lte@^3.2 --save
npm WARN deprecated bootstrap-colorpicker@3.4.0: Package no longer supported. Contact Support at https://www.npmjs.com/support for more info.
npm WARN deprecated flag-icon-css@4.1.7: The project has been renamed to flag-icons
npm WARN deprecated popper.js@1.16.1: You can find the new Popper v2 at @popperjs/core, this package is dedicated to the legacy v1
npm WARN deprecated sourcemap-codec@1.4.8: Please use @jridgewell/sourcemap-codec instead
npm WARN bootstrap-switch@3.3.4 requires a peer of bootstrap@^3.1.1 but none is installed. You must install peer dependencies yourself.
npm WARN tempusdominus-bootstrap-4@5.39.2 requires a peer of tempusdominus-core@5.19.3 but none is installed. You must install peer dependencies yourself

then I add

<script src="https://cdn.jsdelivr.net/npm/admin-lte@3.2/dist/js/adminlte.min.js"></script>

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/admin-lte@3.2/dist/css/adminlte.min.css">

and I get

Error: $.AdminLTE is undefined

var init = async function () {
            $.AdminLTE.layout.activate();

any help would be appreaciated , thanks in advance.
