command to add multiple “secondary groups” for a user in Solaris

I am trying to add 2 secondary groups for a user is Solaris system, but not able to do so. It only adds 1 secondary groups. I've done enough R&D, not sure what to do. Below command I am using :

sudo usermod -g Primarygrp -G Secondarygrp1,Secondarygrp2 TJ252020

when I verify whether groups has been added or not, I use below command :-

id -Gn TJ252020

o/p I am getting- > Primarygrp Secondarygrp1 o/p I want -> Primarygrp Secondarygrp1 Secondarygrp2
