Height map from png height map image

Using Rhino 8, is there a way to import a png height map to convert it to a mesh so I can use it in a CNC carve? I saw this, “Image height to solid_2020May18b.gh” but I don’t know how to use it and my image is larger (1024x1024). I want t create models in Rhino I can carve on my CNC using Vectric Aspire

is the command
_Heightfield
