SRX DDNS with Google Domains

I am running 12.3X48-D25.3 on an SRX210 looking to activate DDNS using Google Domains support for DDNS.  Support article from Google can be found here.

My configs:

[edit system services dynamic-dns]
user@My_FW# show
client vpn.XXXXX.org {
    server ddo;
    agent dyndns;
    username ixwKzS82hwFDAI5L;
    password "$9$GGDjk36CtuBCAM8L7bwmf5F9pRESyevik9pBIleLX7NbYgoZ"; ## SECRET-DATA
    interface ge-0/0/0.0;
}

It seems that the only options for server are:

user@MY_FW# set client vpn.XXXXX.org server ?
Possible completions:
  ddo
  dyndns
[edit system services dynamic-dns]
user@MY_FW# set client vpn.XXXXX.org server

Has any one been able to configure a customer server on the SRX?
