There's a blog post in Guix's blog about this configuration:

https://guix.gnu.org/en/blog/2020/gnu-shepherd-user-services/

I remember to have followed that and I have it working. I had to activate the 
user-level Shepherd by hand in any file that is executed when the system is 
started. In my case I have it in my i3 config. You can put it in .xsession like 
the thread you shared suggests.

Hope this helps.
