Refraction with Alpha Clipping

Hello, I am looking for help to create this effect. I have already started doing it with shader forge. I managed to get the dissolved effect working, but I could never get the refraction to show after changing the alpha clipping. After the alpha clipping slider reaches zero, instead of refracting, it just becomes completely invisible. I know that I might not get direct help towards shader forge, but I would like to know the concept behind it so I could perhaps get it working in shader forge.

Thank you for your time, hope to hear from you guys soon
