System audio not support for screen sharing in IOS

Help
1

I am trying to use the react native webrtc for building a screen sharing application.

I have used getDisplayMedia() for getting the screen share with using a broadcast extension plugin. But currently it does not support system audio sharing. How can i do this?

Also, I have tried to use this function with adding audio parameter but it’s not working and did not getting audio tag from the getDisplayMedia.

const displayStream = await mediaDevices.getDisplayMedia({
        video: true,
        audio: true,
      });

Here is the response of displayStream
{"_id": "AF342A61-BE46-4DF1-9916-7967761E07BC", "_reactTag": "AF342A61-BE46-4DF1-9916-7967761E07BC", "_tracks": [{"_constraints": [Object], "_enabled": true, "_muted": false, "_peerConnectionId": undefined, "_readyState": "live", "_settings": [Object], "id": "553E4FA7-AF2A-46D4-A500-9133AD521B82", "kind": "video", "label": "", "remote": false}]}

Please give me your suggestion.

I was asking almost the same question here: Possibility to share audio along with screen on iOS

As far as I understood, you have to implement it yourself, differently for each platform.
