Modal React component not working as expected.

Shopify Discussion

When using the shopify app bridge Modal component the close(“x”) button at the top doesn’t work.

Here’s the link to the doc.

import {Modal, TitleBar, useAppBridge} from '@shopify/app-bridge-react';

export function MyModal() {
  const shopify = useAppBridge();

  return (
    <>
      
      
    
  );
}

More over can you explain why the primary and secondary action button clicks submit the form?
