How to embed Apache Superset (v1.5) Dashboard in Wordpress?

Question

I'm trying to embed an Apache 1.5 dashboard in a Wordpress site. So far I've succeeded in doing the following:

• Upgrade to Apache Superset 1.5 and enable the embedded dashboard functionality
• Configure dashboard to be embedded
• Implemented backend code to obtain JWT token

What I'm struggling with now is to implement the "@superset-ui/embedded-sdk" functionality in my Wordpress site (using TwentyTwentyOne standard template). I'm trying to follow the instructions listed here: https://fossies.org/dox/apache-superset-1.5.0-source/md_superset_embedded_sdk_README.html

The CDN approach looks the easiest, but I'm getting the error ReferenceError: Buffer is not defined. And if I add the following code:

<script src="https://unpkg.com/buffer"></script>

Then I get the error ReferenceError: require is not defined. I'm not sure how I can resolve this error. Is the CDN approach a dead end, or is there a way I can make this work?

With the "Using npm" approach I'm struggling even more. I'm able to install the npm packages on bitnami linux, but then I don't know how to make use of them in the site. I wasn't able to make it work to add '@superset-ui/embedded-sdk' using wp_enqueue_script(). Also I tried the following code in wordpress:

<script type="module">
import {embedDashboard} from 'http://[MY_IP_ADDRESS]/wp-content/themes/twentytwentyone/node_modules/@superset-ui/embedded-sdk/lib/index.js';
</script>

However then I get the following error:

Uncaught SyntaxError: The requested module 'http://[MY_IP_ADDRESS]/wp-content/themes/twentytwentyone/node_modules/@superset-ui/embedded-sdk/lib/index.js' does not provide an export named 'embedDashboard'

I don't quite understand this error as embedDashboard does appear to be defined in the js file. I also tried using the embedded-sdk/bundle/index.js file with the same result.

I've spent many hours on this and I'm not sure what approach I should take. Can anyone point me in the right direction? Or even better: have a solution to a similar problem with sample code I can look at? If I need to provide more details on what I've tried or what errors I'm seeing let me know.
