Vue3 with Pinia over cdn

I am using shopify to build a front end web app and I have integrated vue into the site and recently realized I needed to start using a store. My question is if there is a way to use pinia over a cdn, I came across this: Using Pinia standalone (CDN or UNPKG) mode · Discussion #1051 · vuejs/pinia · GitHub but it doesn’t seem to be working.

I am using vue 3, the composition api is already in use and the pinia docs only show how to use an npm package.
