SSL VPN

Hello, so my first visit here. I have a question about SSL VPN. A customer from me, needs to access an internal website from everywhere. (mobile devices etc etc.) We always use Secuextender, but this is not available for mobile devices. So i have read the manual, and i see it's also posible to create an ssl connection, by logging in to the USG flex 500.
so far so good, but then it guides me to 
CONFIGURATION > VPN > SSL VPN > Access Privilege > Access Policy > Create new Object > Application

this part is missing in my usg flex. Has this something to do with licenses (if yes, which license do i need?) or is it something else.

the goal is, to first setup ssl vpn, and after that, connect to the internal website.


an other small question, it's also posible to secure the ssl vpn with mfa, i configured it, but its not working at the moment, has this also to do with licenses?


(we just have the basic license)

I hope to hear from you.
