How to install openconnect-sso on Ubuntu 21.04

I would like to install openconnect-ssh. The install instructions from the project seem complex, I'm not sure what pipx is.

How do I install openconnect-sso on Ubuntu without using pipx and using native Ubuntu qt libraries?

I tried to install it using pip, but I got the following errors:
