JavaScript dynamically load script file to create an object and then run .init() on that object [duplicate]

I am trying to dynamically add a script file that is an IIFE object

var DynamicLoadedFile = (function(){
    const id=1;
    const name='Object Name';
    return {
        init: function(){
            console.log('Initialized');
        },
        getInfo: function(){
            return {
                id: this.id,
                name: this.name
           }
        }
    }
})(window.jQuery);

using jQuerys getScript method

$.getScript('script url').done(function(script){
    // TODO: Do something with the script if we want
});

and I don't know how to get the name of the returned object (in this case DynamicLoadedFile) and then use that to run the 'init' or 'getInfo' functions.

i.e. - DynamicLoadedFile.init() or DynamicLoadedFile.getInfo();

I can get the name by using substring on the script that is returned

var objectName = script.substring(4,script.indexOf('=')).trim();

but once I have that I don't know how to use it to call the 'init' or the 'getInfo' methods.

i.e. - objectName.init() or objectName.getInfo();

Does anyone have any ideas? Or suggestions?

Thanks, Tim
