AnyConnect vs OpenConnect

[hanoh haim]

Hi,
I have a working Linux AnyConnect (3.9.0109) with Cisco Server.
I'm new to openconnect and I was wondering if it can work with openconnect

$ openconnect --version
OpenConnect version v8.02.1-1+dde
Using GnuTLS. Features present: TPMv2, PKCS#11, RSA software token,
HOTP software token, TOTP software token, Yubikey OATH, System keys,
DTLS, ESP
Supported protocols: anyconnect (default), nc, gph


:~$ openconnect -u user 1.1.1.1 -printcookie  -vvv --no-dtls

Where can I find the Client Certificate of my AnyConnect?
