I have an object and points (point cloud). I would like to modify the named attribute of the nearest vertex to each point. How to do this?

I tried using the “sample nearest” node, but I couldn’t make a selection out of the output. Then I tried it with the “sample index” node, and it seemed like it was modifying the named attribute for all verticies for each point, or the “sample nearest” node used the source object’s location instead of the point cloud.

I would appreciate some help
