Thanks for the reply:

  1. As our app needs to be run in popped out window (it has WebRTC), it shouldn't matter if Teams has focus or not and whether our app is minimised or not. The whole point of our notifications is to tell the user something is happening so they go back to the app and do something about it.
  2. Our app already has a PWA manifest (although it's not a true PWA as it can't be run offline) and that is another way to install our app. Adding the ability to run inside Teams is a customer requirement that for us isn't right, but that's what they ask for. It's basically being treated like the OS (like a browser can be), where they want to house and run apps. It's bonkers really as the OS is designed for that and they could run our app in any browser or as a PWA, but that's what they all want, everything integrated into Teams. It's a passing fad I'm sure, but it's one we're all having to deal with.
