connecting to Palo Alto Networks GlobalProtect SSL VPN with

I was trying to connect to a Palo Alto Networks GlobalProtect VPN with your latest development snapshot "2022.02.13 (mingw@msys2) - v1.5.3-124-ge9741a6 (OpenConnect v8.10-786-g11181e5f)" located here: https://goo.gl/P88mTi, and when I create a new profile with the gateway domain and click connect, the UI just freezes and nothing happens. I also notice nothing in the log. I was just wondering if GlobalProtect VPN was just not implemented yet? Or if maybe I was inputting the gateway incorrectly? I tried "gatewaydomain.com" and "https://gatewaydomain.com/global-protect/login.esp" and neither works. I was able to connect OK by using the console openconnect.exe --protocol=gp gatewaydomain.com so the problem is just with the GUI.
