Bakery GPU lightmapping 3D baking

Hi everyone,
Hope I’m posting in the right place.
We have Bakery 1.8, and I’m trying to get 3D texture baking working (as a light probe alternative).
The documents state you need to add a Bakery Volume a gameobject. But it’s not a component and I can’t find out had to add it. There’s very little in the way of videos on YouTube for bakery. Can anyone help out?

I believe Bakery has a discord server dedicated to it, maybe you can ask there?
