Camera Popup on TV should start with RTC

Configuration
1

Hello everyone. I’m currently trying to display a popup window with live camera images on my Android TV. This only works if you first try to load MSE and then RTC. When switching between MSE and RTC, the TV pauses. How can I get the popup to load RTC directly?
