Fortimanager configuration for FortiAuthenticator SSLVPN Radius Users

Hello , 

We have setup FortiAuthenticator via Fortimanager and want to implement the

"SSL VPN with RADIUS password renew on FortiAuthenticator" which is described in the following guide "https://docs.fortinet.com/document/fortigate/6.2.8/cookbook/871023/ssl-vpn-with-radius-password-renew-on-fortiauthenticator"

Is there a way to edit the policy via cli on Fortimanager so that I can add the following 2 which are highlighted in bold? 

config user radius     edit "fac"         set server "172.20.120.161"         set secret <fac radius password>         set auth-type ms_chap_v2            set password-renewal enable     next end

I can see via the gui of the FortiManager that the above options exist  eg mschap

but when I look at the fortigate config the only thing that I can see is the following

config user radius
edit "FAC"
set server "XX.XX.XX.XX"
set secret ********
next

Regards
