How to set answeringDTLSRole for PeerConnection

[http600]

I need answeringDTLSRole to be passive, it is here

type PeerConnection struct {
	//...
	api *API
        //...
}

type API struct {
	settingEngine *SettingEngine
	//...
}

type SettingEngine struct {
	//...
	answeringDTLSRole                         DTLSRole
	//...
}

I have found no such exported way to set such option, wondering how to get this work

//No option for DTSL role
func NewPeerConnection(configuration Configuration) (*PeerConnection, error) {
	m := &MediaEngine{}
	if err := m.RegisterDefaultCodecs(); err != nil {
		return nil, err
	}

	i := &interceptor.Registry{}
	if err := RegisterDefaultInterceptors(m, i); err != nil {
		return nil, err
	}

	api := NewAPI(WithMediaEngine(m), WithInterceptorRegistry(i))
	return api.NewPeerConnection(configuration)
}

alright, we can do this

	m := &webrtc.MediaEngine{}
	if err := m.RegisterDefaultCodecs(); err != nil {
		panic(err)
	}
	i := &interceptor.Registry{}
	if err := webrtc.RegisterDefaultInterceptors(m, i); err != nil {
		panic(err)
	}
	engine := webrtc.SettingEngine{}
	err := engine.SetAnsweringDTLSRole(webrtc.DTLSRoleServer)
	if err != nil {
		panic(err)
	}
	api := webrtc.NewAPI(webrtc.WithMediaEngine(m), webrtc.WithInterceptorRegistry(i), webrtc.WithSettingEngine(engine))
