How to get dynamic shadows on translucent surface?

Currently, only translucency volume(surface translucency volume) shadows work on deferred.

I’m trying to get dynamic shadows casted on translucent surface but can’t find how. I’ve read that I should use “per pixel lighting”, which means using the “Surface ForwardShading” as lighting mode in the translucency settings ( Lit Translucency | Unreal Engine Documentation ) but it doesn"t work.
Here are two screenshots with the material set to opaque, then to translucent with an opacity set to 1 for testing purpose (and “Surface ForwardShading” lighting mode)

Setting the lighting mode to “surface translucency volume” which is the default lighting mode doesn’t make the surface to receive a dynamic shadow. That’s why I tryied with the “Surface ForwardShading” mode as it seams to be made for this if I read this correctly : Lit Translucency | Unreal Engine Documentation
Do you mean that something like water surface can’t reveice shadows like this? :
