Preventing access to personal profiles on shared Apple TV

I’m trying to find ways to make the most of the main family AppleTV and still allow flexible use by each member of the family.

we have a generic account set

up for family, but each of us have our appleid profiles. I want the children to be prevented from accessing mine or my wife’s profiles, which have more relaxed settings.

any ideas appreciated.
