Pause/resume the session

Hello, is there a way to pause / resume the session programmatically? It seems to do just that when the app goes into the background and gets reopened.

I am writing an app where I need to access camera during a phonertc session. This screws up the local video stream when I open camera. I am suspecting the fact that iOS only allows only one camera session at a time. However, once I put the app in the background and reopen the local stream gets restored.

If there is no way to pause / resume I would like to know what is happening to phonertc session when the app is going into the background and when coming out of it.

Thanks and thanks for the great plug-in!
