Volumetric Fog not visible in Lumen Reflections

Hello everyone!

Question for you!
I dont now what im missing here and why i didnt notice it before.
But i cant get the volumetric fog to be rendered in the lumen reflections.
Here is an exemple of a scene in UE 5.6. (The plane at the bottom is fully reflective).
I tried a lot of things but ill try any suggestions you may have!
I can provide more info too.

Thank you in advance!
