Is there a method to record video chat app (Google Duo, Skype, Tango, etc.) straight to the phone?

I am trying to record all the video calls with my parents. However, every video chat app that I know does not support a recording option. I have tried 3rd-party screen recording apps but they did not work. It seems the screen recording app clashes with the video chat app for the microphone. So, all I get is a recorded video chat without sound, or a good recorded video chat but the person who I am calling cannot hear my voice. I searched everywhere and even contacted Google support but with no luck. Would it be possible, or would I have to wait for the video chat app to start supporting recording?
