Curious: what do you mean by "integrated"? I'm using Android and Firefox, and it was very simple to just install, login to enable sync, make it my default browser, etc. Chrome is never opened except for apps that don't respect my default browser.

Ok to be fair, last time I tried this out was like 4 years ago. Fuck Google for trying to force everyone to use their proprietary software
Edit: Did you use the native package from your distro? It might have some Google stuff removed. Maybe you would have more success with the Flatpak? https://flathub.org/apps/org.chromium.Chromium
