Draco compressed b3dm file to cesium

Hi! I am Zhenyue Wang from the University of Toronto.
I have been interested in cesium and b3dm files.
I am really new in this field and I want to learn more about this part.
First question is How can I render draco compressed b3dm file.
I built local server to serve my b3dm tileset. And did just like this.
tileset = await Cesium.Cesium3DTileset.fromUrl(
But nothing rendered. The reason is cesium can not render draco compressed b3dm file.
I have searched a log on cesium forum and noticed that cesium not supprt draco compressed file.
So, I extracted glb from that b3dm and the glb is rednered on threejs but not yet on cesium.
Is there any solution for this?
