Yeah our company uses it as of recent. To be honest it's pretty much a 'use it as you see fit' type of platform... there is a php codebase that you can use inside any app, not Laravel specific... I am not trying to be funny on this comment, but reading the intercom docs should be enough to use the package the way you wanted.
I am going to make a statement that depending on what your app does, and finer details of what you want to record in the events for filtering stuff in Intercom, you're going to have to write your own implementation specific to your app, which is really why a tutorial is probably not going to happen.
We just add a few extra event listeners for intercom, and then queue up all the jobs to happen in the background for any type of tracking that we're doing. Just don't make your app dependent on Intercom... make Intercom tap into your app with events, that way you can remove it if need be without being a total pain.
