As far as I can tell, Force Touch capability hasn't been added to Chrome.
This article from April 2017 details what has been released with version 58 (current at the time of this answer). It also goes on to say:
Although beta versions of the browser on the Canary channel included
support for Touch Bar shortcuts on the new MacBook Pro, Google pulled
it from subsequent betas as well as from the stable release as it
wasn’t ready for prime time yet.
It's important to note that there is a huge distinction between Chrome, Chromium, and Canary.
From the Canary page:
Google Chrome Canary has the newest of the new Chrome features. Be
forewarned: it's designed for developers and early adopters, and can
sometimes break down completely.
From the Chromium page:
Chromium is an open-source browser project that aims to build a safer,
faster, and more stable way for all users to experience the web. This
site contains design documents, architecture overviews, testing
information, and more to help you learn to build and work with the
Chromium source code.
Chrome is the "production ready" browser from Google. Chromium is the open source project behind Google Chrome and Canary is the bleeding edge "beta software". It very similar to the relationship of RedHat Linux, CentOS and Fedora.
If you want this functionality, you need to download the respective project and run that browser; it's not something you can enable in the production version.
