Hello, I was trying to implement [Our solution for blurring NSFW content - #5 by bartv](https://meta.discourse.org/t/our-solution-for-blurring-nsfw-content/124584/5) - but unfortunately the code did not work anymore.  
I am kind of stuck here and i couldn’t find any documentation for the discourse JavaScript API in general or how to retrieve custom user fields.

I tried adding the linked code snippet to the header.html section in my site’s theme.  
The object accessible in JavaScript `const user = api.getCurrentUser();` seems to contain a property `custom_fields` not `user_fields` as it is in the referenced posting.

However it is empty, or i don’t know how to properly query/fill it. I’m getting the feeling i would need an actual Ruby plugin to access this data.

I would really appreciate any help on this issue, or guide how to specifically get the same functionality working again.  
The feature i need is adding a custom css-class to the body depending on a custom user field.

Thanks for reading o/
