How to organise maps for exporting to Sketchfab/Unity

[Impface]

I want to be able to export models with enough info to make them look good - roughness maps, normal maps, subsurface maps etc.

I’m struggling to find out how each baked map plugs into the nodes in Blender prior to exporting. I know how to do diffuse maps, roughness maps and normal maps, but I want to know how the other types work too - do I apply them in Unity/Sketchfab, or can they be embedded within the file?

I believ ei answered this in the Udemy Q&A but to add here for completion.
The textures are exported from blender as texture files and then imported independant of the model into unity and reconnected into that system
There is no textures come over with blender into the game engine as just work as if it does its mostly luck that blender and unity have them int he right place
