LuxBlend25 glass 2 HOW DO I USE?

i have been using lux render for months now, and it occured to me tha i like glass 2 more than glass, but when i select the option, theres no settings and a blank preview in the view port. i have seen other people use it, but no documentation, can someon tell me how to use it

Glass2 docs are over here:
Also, for use in Luxblend25:

In short, you need to make a volume and set it as the “interior”. Glass2 is basically an empty shell for the volume. Hence why it hardly has any params of its own.
