Where can I delete wifi's configured with BerryLan?

I try to delete a WiFi connection I created with BerryLan on a Raspi. When I look into /etc/wpa_supplicant/wpa_supplicant.conf there is only this:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

Is there another file where they are configured?

Thanks!

You can remove the using nmcli.

You can liste the configured networks using

nmcli c

and then delete or disconnect (down) using

nmcli c  delete <[id | uuid | path]>

dankeschön that worked!
