Green In-Call status bar vs red Recording?

Hello,
I developer voip functionality for my clients app.
It uses googles WebRTC sdk + callkit.
The problem is when I put app into background (.voice and .voip modes enabled in pList) while on call I get red Recording status bar. My clients would like it to be Green like WhatsApp, Skype and native calls app.
I can not find any documentation how it is done. All I found is some comments that say Red Recording bar is because I'm running AVAudioSession on .playAndRecord category ( .voiceChat mode) in background.

Can anyone instruct me/point me to documentation/example on how can I enter In-Call background state with green status bar?

Sincerely,
Martynas
