Cant find Mesh Display in Speckle 2.20.3

There is a tutorial on Speckle website shows how to bake a speckle object coming from Revit in rhino through Grasshopper. However in new Speckle there is no mesh display in types!
I would like to separate Revit families and then bake them in Rhino!

Could you share which tutorial this is? If it’s particularly old we can seek to renew it (or retire it)
