Thanks to you both. The missing icons don't bother me much, but since we're
at it, here we go

The line

source "$HOME/.guix-profile/etc/profile"

already is in my .bash_profile file

The $PATH contains a bunch of guix related paths (starting with
/home/catonano/.guix-profile/bin: ... )

But the .guix-profile/etc/profile file doesn't even mention any
XDG_DATA_DIRS variable

In fact, echo $XDG_DATA_DIRS shows an empty line
