3. For the cron job, I recommend doing echo "cd $(pwd); npm start" > uci && chmod +x ./uci && sudo ln -s $(pwd)/uci /etc/cron.daily/update-calendar-icon
4. npm install.
5. cp ./.env-example ./.env
6. nano ./.env edit path to svg

To assign svg to calendar app, in nano /usr/share/applications/org.gnome.Calendar.desktop replace: Icon=org.gnome.Calendar with Icon={PATH_TO_SVG}/calendar.svg
