Visited today without charging.
The charger is in front of the garage, on the main road side.
The official access is through the gas station, or from the back road through the covered section. You could also turn off the main road against the McDonald's exit but I don't think this is permitted. You can also drive to the end the back road, through McDonald's parking and then enter the access the charger just before exiting onto the main road, as I suspect the Zoe in my pictures did.
It doesn't look like there's a proper parking spot assigned to the charger. The last yellow spot was occupied by a demo vehicle, but there's some space in the white area after the charger as well.
The eCarUp QR code is installed. The charger is a Schneider DC rated for 24kW / 65A / 200-530V. There's a name "nünlist" on the sticker which I assume is the company who installed/manages the charger https://www.nuenlist.ch/
