Audio/Video playback while on a phonecall

I think this may be a simple overlooked detail ( Only Samsung Internet has implemented this from what I have tried) but I would like to be able to listen to and play videos while on a phone call on Android. It is quite a bad user experience to have to swap browsers or hang up the phone when someone wants me to look at a video they just sent me while I am on the phone.

Currently video will play if I silence the audio but will not play if audio is on.
