How about adding content for using Power BI within Microsoft Teams? My company has just made Power BI an available app in Teams and, though the infrastructure has been put in place, it's not obvious what's going on behind the scenes. I started the Maven Power BI Service course hoping that it shed some light, but it didn't look like it was going to. With Teams' adoption rate, a few chapters in the applicable course(s) would benefit a lot of organizations.
