After getting the shape or shape base object, you can get the image source by using the shape.toImageSrc() API.
You can get the shape image sourc using the following code:
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import './styles.css';
import { AppFunc } from './app-func';
import { App } from './app-class';
// 1. Functional Component sample
ReactDOM.render(<AppFunc />, document.getElementById('app'));
// 2. Class Component sample
// ReactDOM.render(<App />, document.getElementById('app'));
