hello. I recently asked here for help with Lemmy HTTP API and someone said "why don't you use lemmy-js-client?". i tried to add it and...

first i searched the internet about this library and it turns out that it is an npm library... (I have github pages) i searched different variations of the library and found a cdn version of it. i tried to add it. it was a hell of a torture.... i added it the way I add cdn libraries, nothing. i searched all over the internet, but found null. i even asked chatgpt! to no avail. the library (and everything I tried to get out of it) turned into undefined!

what am I supposed to do? this is cdn version what i tried to add
if u want here is source code
