Adding a Normal map to a simple plane

Hello everybody,

I'm using ofMesh to create a plane in 3d with lights and material. I want to further add some roughness to the plane with a normal map. Looked around the forum for an example along the same lines, and I've got this link so far - https://forum.openframeworks.cc/t/specular-mapping/22400

Looking at a shader example to add this to the plane. Here is the normal map i want to use on the plane.

Thanks in advance,
It's a great forum. Cheers!
