Hello @makomeyer and welcome to the forum!
As was said, firstly you need to register on google analytics and generate your gtag.js and then just add code from this post: Adding google analytics tracking code to dash app - #6 by takaakifuruse
replacing the gtag part with your own.
When everything is set up you can see the visited pages in Reports section → Engagement → Pages and Screens. From my experience it updates once a day at midgnight US time.
When it comes to tracking individual interactions, I don’t have any experience with that. But maybe somebody does and I will be also happy to learn how to do it
