There's a cool detailed overview of the location on the reference page from the company https://sts-emobility.ch/referenzen/nibru-immobilien-ag The document says the chargers were installed in June 2020.
However there are a few things that don't match anymore.
The document and pictures show a 30kW DC charger that is not currently visible on eCarUp.
There are 4 additional chargers for parking spaces 35 to 38 which did not exist at the time of the document. Those might be private and not public. We see the parking in the pictures but there were no additional chargers at that time.
