Hey Alf! Thank you for sharing your setup. Have you looked into using OBS[https://obsproject.com/] for this? It offers very convenient audio routing, even without using JACK. In the past I used all sorts of complicated setups, but now I simply fire up OBS and off I go. Especially if people can use an online solution and not a phone - you'd be all set!
