How to get avatar stream to livekit?

Is there any way to get avatar streamed (or ingressed) to my livekit room? Right now, the heygen avatar streams from a livekit and hence, i am unable to use it as an agent/track in my livekit room. I have a complicated app where i want to publish multiple tracks and orchestrate between them. However, i can't figure out how can i stream the avatar to my livekit room using websocket. Please guide on this, since you've written that Raw WebRTC will not be supported in future updates. And the livekit version doesn't support it (or i am unable to figure out the same).
