Are there plug-ins loaded TLE Cesium

Is there any front-end plug-in that can directly load TLE data into Cesium? I used Python to convert all TLE data of satellite debris, and the CZML of conversion result reached 600M directly. If only a small amount of TLE data is converted, there is no problem. However, even if it can be loaded, this background conversion method is not efficient in the first place, and the conversion result is still so large, the transmission efficiency is also a problem. I see the fragmentation 3D system of Celestrak, After TLE data acquisition was completed, the system soon carried out 3d display, and I felt that it was not changed to CZML through the background. I don’t know how Celestrak was done, if you know, please let me know, thank you.
