Check if user is mute

1

Hello,
how can I know if the user is in mute in the front-end code (react code)

i found this :

 _isAudioMuted() {
        return this.props._audioMuted;
 }

I want to change the color of the displayName when _isAudioMuted return false,
I didn’t find where I can change the text, or where I can find the event to add the icon mic to the display name once the user is muted

thanks
