The article does also say MacOS11, but with a little deductive reasoning you can figure that out. Chrome runs on BigSur and newer so if you have Monterey and are running Chrome it is newer than BigSur. Next year they drop support for BigSur but since Monterey is newer than BigSur you can still run Chrome.Articles like this sure ducked the point home for the new versioning scheme with number instead of nonsense names. Is Monterrey before Big Sur or Lake Tahoe or whatever? I have no idea.
Easy peasy if you use your noggin.
