Cant find /ip ipsec policy group

Hi I am running 5.24, and I am following the L2TP instructions where it mentions:

/ip pool
add name=RW-vpn ranges=192.168.250.2-192.168.250.254

/ip ipsec mode-cfg
add address-pool=RW-vpn name=RW-cfg split-include=
192.168.254.0/24,192.168.253.0/24

/ip ipsec policy group
add name=RoadWarrior

I cant find the /ip ipsec policy group, policy group is not shown under /ip ipsec in the terminal. I already have the security package installed.

[admin@RouterOS] > /ip ipsec policy group
bad command name group (line 1 column 18)
[admin@RouterOS] > add name=RoadWarrior

Is this a version 6 feature, or am i missing something?

This is only v6 feature.
