Video Door Bell 4 Wedge Kit

Hello, I have a VDB 4 mounted on brick. I am trying to find out if to use the wedge kit, I will I need to remove the original mounting bracket from the brick and make additional holes for the wedge kit and then attach the original mounting bracket to the wedge OR does the wedge kit attach to the mounting bracket itself and its just a matter of removing the camera and adding the wedge and then the camera on it? Thank you very much for any information, I hope I was clear in my description.
