Call Function from Blueprint Function Lib in C++

I want to call the function “GetLightMaterials” from a BlueprintFunctionLibrary. But can´t get a reference to this function. LoadObject seems to be ok but FindFunction doesn´t work for me.
I tried this code:

Why do you put parentheses there?
That is not part of a UFunction’s name.
