Unable to use Web Components

[DatReki]

When I try and call the components directly from the unpkg CDN (listed here) e.g:

<script src="https://unpkg.com/@glyphs/wc-core" type="module"></script>
<script src="https://unpkg.com/@glyphs/wc-brands" type="module"></script>
<script src="https://unpkg.com/@glyphs/wc-flags" type="module"></script>

I get the following error:

Uncaught ReferenceError: assignment to undeclared variable parcelRequire
wc-core:1:988

And the following warning:

Source map error: Error: request failed with status 404
Resource URL: https://unpkg.com/@glyphs/wc-core
Source Map URL: /index.js.map

(Same errors and warnings with wc-brands & wc-flags)

When I try the files locally (downloaded through jsdelivr) I get the following error:

Loading module from “https://localhost:7209/lib/glyphs/wc-core” was blocked because of a disallowed MIME type (“”)

Granted unsure if you have to call the library otherwise when used locally.
For reference, my codebase uses ASP.NET with .NET 6 and I use libman to grab the library locally but that shouldn't matter when it comes to this issue.
