[feature Request]: Allow audio playback during phone call

[somombo]

When I am on a WhatsApp call the app disables playing all audiobook. I haven't tested this on a regular call but I assume this is setup this way by design. Please consider allowing playback during phone calls in the same way that we are able watch (and hear the audio of) YouTube videos from youtube app or browser. I also note that the spotify app plays audio content just fine even while someone is on a call (albeit at worse audio quality but thats preferable to no audio)
