Has anyone integrated Windchill to MS Teams?

I am aware of Fishbowl's MS Teams offering. I was not particularly interested in that type of customization. I was looking at more of user presence and communications. We've done some internal work at simple URL icons to invoke a Team's message to a user. This can be done via a Data Utility to add in a Teams icon and work similar to the email link. 

From what I've read, to do anything more advanced, we would need to register an application in Azure, get an ID and use that to make calls via Microsoft Graph API. If I need to pull live information like online status info or a hover over popup, that would need some custom calls.

What would be nice would be to have Windchill message users in Teams about events as an alternative to email communication. Its about time. I also see that PTC has the Windchill Office integration where you do the same thing, register it as an application. This means the foundational code is already there. Does anyone know where that might be or if the integration credentials can be extended for custom enhancements like I mentioned above?
