Installation was easy enough in Launch, but I did not see the download of any associated resources in my network monitor when browsing the site after installation. Incidentally, I ran into the same behavior when using Google Global Site Tag (gtag) provided by Acronym, as well.
I was able to get the "Google gtag" extension provided by Adobe working (I can't find the extension page to link here). Upon installation, I see network requests to download the gtag.js from googletagmanager and the subsequent collect beacon to google-analytics.com. The only problem with this extension is that it has almost no configuration options. For example, you cannot have a different UA# per environment as you can with the Google Universal Analytics and Google Global Site Tag (gtag) extensions.
