Enable Zones assignment on user SSO login

Hi,

I need to enable Zones assignment on user SSO login and in the section "Configure Zones Assignment with Single Sign On(SSO)" there is a message that says "please submit a ticket to Box below. Once Box has enabled Zones SSO, you will be able to configure here." Contact Box
I need assistance to enable Zones, because I've just completed the SSO activation successfully in my Box environment.
Thanks.
