Video conferencing with Gamelift and UE

Hi, my team is currently exploring to have a in-house conferencing solution based on (multiplayer) gamelift in UE environment. Have anyone of you ever thought / made something like this? If so would be glad to hear your thoughts and ideas. I guess 10 concurrent participants with switched on cameras and microphones should be a great start. We look at having the zoom functionalities (or at least some of them) but in a beautiful 3d environment.
