How to add local candidate when peer connection of ion-sfu is set ice-lite.

Hi team,

I created a peer connection and set it as ice-lite and passive status like below, but I failed to find the way setting local candidate for it. How to set the local candidate when peer connection is ice-lite?

    se := webrtc.SettingEngine{}
    se.SetLite(true)
    se.SetEphemeralUDPPortRange(9090, 9090)
        se.SetAnsweringDTLSRole(webrtc.DTLSRoleServer)
    se.SetNetworkTypes([]webrtc.NetworkType{webrtc.NetworkTypeUDP4})
    se.SetNAT1To1IPs([]string{"x.x.x.x"}, webrtc.ICECandidateTypeHost)
        ...

        api := webrtc.NewAPI(webrtc.WithMediaEngine(&me), webrtc.WithSettingEngine(se))
    pc, err := api.NewPeerConnection(webrtc.Configuration{})

The answer generated is below, and there is no candidate.
