Umbrel on a 802.1x WiFi network

I’m wondering whether anyone has successfully set up Umbrel on a Raspberry Pi that access the internet over a wireless network with 802.1x security. I can’t share my WiFi connection over Ethernet because of the 802.1x security. And the steps for connecting the Raspberry Pi to WiFi don’t work because I have both a username and password for the network. I’d appreciate any help.

Thanks! It’s EAP-PEAP.

So I created that file and named it wpa_supplicant.conf

Changed the country and SSID and identity and password. Tried it with and without the phase1.

Still didn’t work.
