how to allow camera and microphone in the middle of the teams call?

[ank-007]

I want to allow camera and microphone permissions dynamically if i connect the microphone and camera while teams call is already running in edgewebview2, I am initially launching the webview like this

std::wstring args;
args.append(L" --ignore-certificate-errors");
args.append(L" --hide-scrollbars");
args.append(L"--disable-features=BlockThirdPartyCookies");
/ANK 29-01: just leaving this commented, might be useful if we decide to play videos muted/
// args.append(L" --mute-audio");
args.append(L" --autoplay-policy=no-user-gesture-required");
// args.append(L" --auto-accept-camera-and-microphone-capture");
if(scrn == 0)
{
args.append(L" --auto-select-desktop-capture-source="Entire screen"");
}
else if(scrn ==1)
{
args.append(L" --auto-select-desktop-capture-source="Screen 1"");
}
else
{
args.append(L" --auto-select-desktop-capture-source="Screen 2"");
}

qDebug()<<"args are "<<args;
auto options = Microsoft::WRL::Make<CoreWebView2EnvironmentOptions>();
options->put_AdditionalBrowserArguments(args.c_str());


Microsoft::WRL::ComPtr<ICoreWebView2EnvironmentOptions5> options5;
    if (options.As(&options5) == S_OK)
    {
            options5->put_EnableTrackingPrevention(FALSE);
    }

qDebug()<<"options are ready";
HRESULT res = CreateCoreWebView2EnvironmentWithOptions(
    nullptr, userDataFolder, options.Get(),
    new webview2_com_handler(wnd, cb,
                             [&](ICoreWebView2Controller *controller) {
                               m_controller = controller;
                               qDebug()<<"got controller"<<controller;
                               m_controller->get_CoreWebView2(&m_webview);

this code suppresses the permission popup which comes initially but how to make it allow dynamically. when i try to mute / unmute with microphone connected , it says to allow microphone from omnibar, but i run the teams in headless/ app mode which doesn't show any omnibar, Any help is appreciated :)
