How to connect to a VPN network via Anyconnect?

Question

VPN

There is access to the grid but I don’t know how to connect, the access looks like this: https://sslvpn.sitename.com/+CSCOE+/logon.html user :password

softinu but what to do next, how to actually get access to the grid?
In the MAC, I went into the network settings, added Cisco IPSec and entered the data - to no avail.
When trying L2TP - also unsuccessfully.
