Apple

Hi. Old iPhone SE I need to set up for my son. Completely reformatted. No other iPhones on the Apple account anymore. Is there a shortcut to directly set this up for a kid? Objective: Disable specific apps, don't allow installs and set bedtime limits. Apple assumes I have a "Parent" phone. And when they don't, the instructions don't match anything on the screen. In fact, screen time is only accessible after answering several prompts and then it gives errors when I enter account info (seems to allude to another account (child?) but not prompting for it). OS version is 15.8 (probably the last supported OS for this phone)
