Sequencer and Billboard objects

Hi, I’m trying to make a movie with Sequencer.
The structure has static mesh,cinematic camera and Billboard objects.
I want the Billboard objects to follow the camera no matter how I move it.
Naturally, the Billboard object does not register a Keyframe, but must be rotated by the camera sequence.
Please let me know how I can do this.

The condition is to use Path Tracer renderer. I used a Billboard component but it didn’t render.
