We have build a free (simple) Intercom extension for magento 2.
You can find it under https://compactcode.eu/intercom
It is currently being reviewed as an app for the app store of intercom also.
We would need some test studies. It is free to install.
So if you have a Magento 2 webshop feel free to install at and give feedback!
You can find install instructions on the page.
