Oven Handle Came Off Superba Range

The handle came off of my oven door. We removed the door, and have removed the side plates. We still cannot find any screw or clip to take the top plate off, which must be removed for us to reattach the handle. This should be easy. How do I remove this top plate, in order to slide out the glass front?
