Theme issue when using ESM version

[vnihoul77]

I'm using a rather strange integration of PopupPicker as I'm limited in the environment I am working in.
Therefore, I am importing PopupPicker in the following way:

HTML

<script type="module">
import { createPopup } from 'https://unpkg.com/@picmo/popup-picker@latest/dist/index.js?module';
window.createPopup = createPopup
</script>

JS
const picker = createPopup({},{})

However, this seems to trigger errors as I am using the theme option.

Here's how it appears without specifying a theme in options (Fiddle):

Any hint?

Fixed using
<script src="https://unpkg.com/picmo@latest/dist/umd/picmo.js"></script>

and in options:

theme: picmo.darkTheme
