VIdeo Doorbell corner kit for mounting

Anyone had to use a 90 degree corner kit to mount the video doorbell camera?  My doorbell is on a wall that is perpendicular to my front door that makes it necessary to turn the camera 90 degrees to view the approach to my door.  Simplisafe advised they only have a small wedge (it appears to be about 15 degrees) and that the wedges cannot be stacked to achieve 90 degrees.  I see that Ring makes a 90 degree corner kit but am unsure if the Simplisafe video doorbell will mount properly to this kit.
