Using Pi4 Wifi Setting Umbrel 1.1

I am using Umbrel 1.1 on Pi4 and trying to connect wirelessly . I was able to get that working on the previous version using SSH via adding network connection to

/etc/wpa_supplicant/wpa_supplicant.conf

Its seems that 1.1 is using different “locked down” restrictive version. but Thanks for adding adding the terminal option

Is there a way to enable wireless connection.
