adding custom package to guix home

[rdes]

Hello,

I'm trying to add emacs-svg to my package list in my guix home configuration, 
but I'm getting "no code for module (emacs-svg)" error when using use-module​ 
and "guix home: error: emacs-svg: unknown package" error when I include the 
package definition in the guix home configuration file.

I've added my configuration files my snippets:

Thanks,
