Low poly to high poly

Good Morning, I am trying to project the details of a high poly model to a low poly model using a normal map. Sorry if I’m doing something wrong that is very basic but I’m new to unreal engine and relatively new to 3d.

I understand that assigning a normal map from the high poly version to the low poly model causes the details to be projected, however, in my object the polygons of the low poly version are still noticed (attached photo).

There is no way in UE4 that allows you as in substance painter to select the object in its high poly version to project directly from this model the details?
