Chrome browser ignoring parental controls

I'm running MacOS 10.13.6 and it seems that the Chrome browser is ignoring the parental controls that I've set up for kids' accounts. If I try to go to a particular website in Safari it blocks it. However, that very same website is allowed in Chrome. Is this expected behavior? Is there something I can do to make Chrome follow the parental rules?

This is the expected behavior, parental control only apply to the applications provided by Apple. At the time we needed that, we just blocked access to other applications through Parental Control.

There are parental controls built into Chrome. The concept of parental controls in the Chrome browser, revolves around supervised user profiles. If a child is forced to browse the web while signed in under one of these restricted profiles, their parent or guardian has the final say regarding where they go and what they do while online. Not only does Chrome allow you to block specific websites, but it also creates a report of which sites they actually did visit during their browsing session.

The step-by-step instructions for setting this up is given here.
