The functionality was introduced in this PR
I asked and verified that the GUI notification had not been tested
I exercised it while testing a more recent PR that updated the wording

The notification mechanism is nottify-send. I verified that invoking that on command line does show a notification on my system

The invocation of notify-send seems to be the problem. Trying this manually on command line gets:

❯ notify-send \
          --app-name Snap \
          --urgency normal \
          --icon dialog-warning \
          "Snap has ${CONFINEMENT} confinement" \
          "Snaps will stop working in early January 2025." \
          "See ${URL} for details."
