I managed to launch the app by mixing the command above with some parts of the command used in another message about the same subject (https://lists.gnu.org/archive/html/help-guix/2020-07/msg00012.html). So this worked:

EXAMPLE:
guix shell -C -E "^DISPLAY$" -E "^XAUTHORITY$" --expose="$XAUTHORITY" --share=/tmp/.X11-unix/ --share=$HOME/.Xauthority
END EXAMPLE

But I'm just typing things without much consideration and hoping for the best :) For example, the application now starts but it has no icons. So I guess I'll go find some information about all the fundamental variables and resources required by GTK apps to run.
