How to download old Google Chrome for macOS Catalina 10.15?

It takes a bit of digging to find it but here you go:

• The last supported version for users on macOS 10.15 Catalina is Brave version 1.69.168 and Chromium 128.

Brave 128.1.69.168 (should be about the same and better as Chrome) and Firefox 147.0.3- should work in Catalina.

Google Chrome requires a newer operating system. Is there a reason you need it?

Hint: No one needs it.
