when following the Shopware guide .html

const PluginManager = window.PluginManager
const Plugin = PluginManager.getPlugin('CookiePermission')
const PluginClass = Plugin.get('class')

export default class MyCookiePermission extends PluginClass {

}

it return the following error :

enter image description here.

worth mention that direct imports with path work. but i cant use them as the project will be loaded trough composer.

override the main plugin to be able to extend its functionality using the Plugin manager method

const PluginManager = window.PluginManager
const Plugin = PluginManager.getPlugin('CookiePermission')
const PluginClass = Plugin.get('class')
