The documentation says that we're supposed to use defineWindowMessaging in order to communicate with an iFrame, but since it's missing an example, I can't figure out what's missing, but I never seem to receive the message.

// content script
import { windowMessaging } from '@/windowMessaging';

export default defineContentScript({
  matches: ['<all_urls>'],

  main(ctx) {
    // Define the UI
    const ui = createIframeUi(ctx, {
      page: '/app.html',
      position: 'inline',
      anchor: 'body',
    });

    // Show UI to user
    ui.mount();

    setTimeout(() => {
      console.log('content: sending test');
      windowMessaging.sendMessage('test', undefined);
    }, 5000);
  },
});
// iframe
import { windowMessaging } from '@/windowMessaging';

windowMessaging.onMessage('test', () => {
  console.log('iframe: received test');
});

This is probably what you're looking for:

windowMessaging.sendMessage('test', "*");

If that doesn't work, I need more info. How are you loading that // iframe code into the iframe? Do the iframe and parent frame share the same domain?
