How to apply IIFE in ReactJS + Typescript?

I would like to use IIFE in ReactJS + Typescript environment. So i rewrite this code with ReactJS + Typescript

IIFE

(function() { 
        //Constructor
        this.Radio = function(){ 

            var defaults = { 
                locale: "en-US", 
            }

        } 

        // Public Methods   
        Radio.prototype.load = function() { 

        } 
      }());

ReactJS + Typescript

    export default class Radio{
    options: any = { 
        locale: "en-US", 

    };
    constructor(props: any) {
        var defaults = { 
            locale: "en-US", 
        }

    }       

    // Public Methods   
    load = () => { 
    }
}

What i try to achieve is when the bundle.js load from html page i'm able to instantiate by passing some value in like below

<script src="main.js"></script>
<body> 


    <div id="app"></div>

</body> 

<script>
    $(function() {
        var test = new Radio({   <----error on this line         
            locale: "en-US",            
        });
        test.load();
    });
</script>

But when i run above code i got this error Uncaught ReferenceError: Radio is not defined

Is that possible to implement IIFE like above?

Thanks

If you want this old code to still work you need to put Radio on this just like old times. E.g.

 export default class Radio{
    options: any = { 
        locale: "en-US", 

    };
    constructor(props: any) {
        var defaults = { 
            locale: "en-US", 
        }

    }       

    // Public Methods   
    load = () => { 
    }
} 

// ADD
(window as any).Radio = Radio;
