Use UVs to map image in geometry nodes

(apologies noob question)
I’m using geometry nodes to delete polygons based on the alpha channel of a texture.
Its working ok expect I can’t see an obvious way to use the UV coordinates to map the image.
I was hoping for some sort of UVmap node similar to that in the shader node module.

The geometry I’m using is just a plane so I could just do some maths to offset the vertex coords to get the image position I want, but its a bit of a pain, and obviously would only work with a plane. Feels like you should be able to use the UVs on an incoming mesh.

Is this possible, am I missing something?
