Convert X2GO config using proxy server to ssh config file

Question

I would like to convert my X2GO connection config to a more usual ssh config file in order to use the VS Code in remote mode. But with this proxy server, I'm really lost.

Here is my X2GO configuration setup.

Here is my attempt:

Host domain
Hostname H
User login
Compression yes

# Automatic connection to hosts behind a firewall
Host *.domain
ProxyCommand ssh domain "nc `basename %h"
User login
Compression yes
