Replacement security screw for Ring Doorbell Elite

Does anyone know the size, or have a link to purchase, a replacement security screw for the Ring Doorbell Elite?Twice I have called Ring support, and they very kindly ordered me a "Elite Screwdriver and Security Screw" (per the Customer Support email confirmation) but what actually arrived in the mail was only a screwdriver, no screw. In both cases the packing slip indicated "Ring Elite Screwdriver" (ASIN B089QZJ1KG). Or can a Ring Support person tell me what specific ASIN to request that includes the screw? Is the screw perhaps bundled with the faceplate instead of the driver?I would gladly pay $2 for an assortment of replacement parts, which seems to be available on Amazon for all doorbell models except the Doorbell Elite. Unfortunately, the Elite seems to use a different security screw than all the rest (I have confirmed it is at least different from my Doorbell 2).Alternatively, I'd be happy with a screw that isn't super secure (e.g., not a proprietary driver, just a Philips screw in the right size would be fine).
