Check collision on the sides

Hello, i tried to check whenever my player hits Right or Left, then it have to do something. But it doesn't seems to work. I use C# and here's the code. This is meant to be called from another class, just to make that clear.

     void checkCollisionSide(Collision hit) {
         Vector3 relativePosition = transform.InverseTransformPoint(hit.contacts);
         
         if(relativePosition.x > 0) {
             print("RIGHT");    
         } else {
             print("LEFT");    
         }
     }
