Extend plugin javascript file from another plugin

Question

Is it possible in Shopware 6 to extend plugins with another plugin? I have plugin A from the shopware store, I need to change its functionality a bit, because it does not quite suit me. This plugin overrides core functionality of shopware - ListingPlugin from src / plugin / listing / listing.plugin. I need to get the js file from plugin A from my plugin B or from theme. I didn't find any information on this functionality from documentation

You can extend the plugin like

import ExtendPlugin from './plugin/youtPluignFolder/extend-plugin.plugin';

const PluginManager = window.PluginManager;
PluginManager.override('OrgPlugin', ExtendPlugin);

...

After register the file you need to create the file. There you can extend or overwrite the function like

import OrgPlugin from '/app/custom/plugins/pluginName/path/to/plugin-file.plugin';

export default class ExtendPlugin extends OrgPlugin {
    init() {
        super.init();
    }

    // Function you want overwrite or extend
    function () {
      //    your code
    }
}
