Hiding an emitter from view but enjoy its reflections

When I hide an emitter from camera - it emits and is visible in reflections, but it blacks out what is behind (an acrylic material)
When I hide an emitter from camera and reflections/refractions - it stops emitting

Any ideas or tricks on how to make an emitter invisible from the camera - but have it show up in reflections/refractions? Thanks!

Solved. I forgot about the "ghost" BSDF trick to be used in an emitter-MXM, if the emitter must be hidden.

So did I. How does it go, again?
