Video Doorbell Pro and existing doorbell - UK

I had read that it was possible to wire the Ring Video Doorbell Pro in addition to an existing doorbell, so that you replace the old doorbell button with the Ring and connect it so that the old doorbell chimes when the Ring button is pressed.I’ve just received our Ring Video Doorbell Pro with plug in adapter here in the UK, but I can’t find any information on how to make this work, and there’s no Pro Power kit in the box.There is a doorbell bypass device in the box, but I don’t want to bypass it, I want to include it.Is it possible, please?
