Hmm I manage to find a workaround, a little bit manual though.

1. Install rootsh
2. go to terminal
3. sudo gainroot
4. openconnect <servername>
when using this command line interface, the group name is visible and i am able to connect by typing the group name, user id and password.

the problem is the DNS and the routing is not configured yet, so I need to add that manually by creating 2 scripts
1. company.sh --> for all the routing and dns
2. normal.sh -> back to use the default routing and dns

For now its sufficient since I am able to vpn to my company using this workaround.
