It’s part of the open source chromium engine.

Here’s how it implements some of the privacy sandbox stuff for example: chromium.googlesource.com/…/privacy_sandbox/

and here’s some of the Topics API stuff: chromium.googlesource.com/…/browsing_topics/

Theoretically they could still inject malicious code even if the stuff in the chromium source code looks fine. Given they got sued for their servers still tracking you while Chrome was in Incognito mode (even with the warning every time you open Incognito mode), I’d imagine any injection of code like that would result in another lawsuit (or several). At some point you either have to trust that Google is implementing things how they say they are in the code that they put out or just use a different browser.
