Plastic or glass Button emitting light in Eevee

I’m trying to create a material for a button on a music control panel. It looks like a plastic glossy button with some colourful light coming from behind.

I’m using EEVEE engine, so I tried bumping the transmission to 100% and also checking the refraction in the render settings, but it’s not the best looking button, it seems not transparent.

Hey,
I got a sample blender file with a button that may help.
