Why don't sun rays reflect in mirror in path tracing mode?

I have a scene with a mirror hit by sun rays. I would like to see the effect and trace / control where the sun rays hit, but the mirror doesn’t reflect the sun rays.

Why aren’t sun rays reflected in mirror?

I have tried all the settings imaginable… Is there a setting I may have missed?

Is a sunlight reflecting mirror (or glass) a feature that may be available in future Twinmotion versions?
