Storybook composition

[PatrickMunsey]

I've setup resium in a react-vite storybook and it's working well for me to develop some custom components. I'm now trying to 'compose' the already published Resium storybook for the core components at https://resium.reearth.io/examples but am unable to do so.

Some notes:

• Some information about storybook composition here and here
• My attempted implementation

// maint.ts
import type { StorybookConfig } from '@storybook/react-vite';

const config: StorybookConfig = {
  refs: {
    'external-reaviz': { // example of a working composed storybook
      title: 'Reaviz',
      url: 'https://reaviz.io',
      expanded: false, 
    },
    'external-resium': { // Trying to get resium storybook composition working
      title: 'Resium',
      url: 'https://resium.reearth.io/examples/',
      expanded: false, // Optional, true by default
    },
  },
};

• The Resium storybook is hosted on the /examples subdirectory. The other storybooks I've successfully composed are on the base path. This probably isn't the cause but it is one thing different.
• I've noticed a CORS error when pointing directly to the index.html file. I'm wondering if your hosting CORS config may be limiting the ability to compose the storybook
• I'm using storybook v7. I don't think there should be an issue with this if you are still using v6 though.
