Internet Parental controls

Hi! I’m trying to use parental controls and downtime schedules in the Xfinity app, but my app only shows WiFi and Advanced Settings — no People or Security tabs.

My gateway is a Technicolor XB6 (model CGM4140COM, MAC [Edited: "Personal Information"]).

Could you please provision my account and gateway for xFi / Advanced Security so I can use People profiles and parental controls?
