Walked around last week but didn't see any charger outside.
Based on the name and coordinates, I assume it must be in the underground parking named "Senevita Besucher". There are ticket gates.
On Chargemap there are pictures for the Swissrenova chargers. Those are different chargers on eCarUp, but there's no way to say for sure which chargers are in the picture, as there are no QR codes or instructions visible. There's also a possibility both are in the same underground parking https://fr.chargemap.com/swissrenova.html
