The function name of React of Shopify POS application development

[hashi_ws]

Shopify by extension over embedded POS Appley POS link of the POS application, add two tiles
I want to but, function name of React you are in trouble without displaying the screen other than the Example.

import React from 'react';
import ReactDOM from 'react-dom';

function Example() {
  return (
    <div>
      Example
    </div>
  );
}

export default Example;

Build the above, but when you view "Example" is displayed on the Shopify POS,
function you will not be able to display to change from Example the name.
