Rotate camera follow the normal vector

I can get a normal vector from a triangle on the mesh, then I want to rotate the camera to face this normal vector, but I don’t know how to do that

I can draw the green line from the position of the triangle with the normal vector direction and move the camera to the end of the line, now I only need to rotate the camera to face this direction so I can see the triangle position

Thank you!

You can use the Transform.lookAt(Transform transform) by specifying the transform you want your camera to look at. Here you will probably use the center of the triangles associated to the normal.
