Change the sound of the ring doorbell

How do I change the sound that the DOORBELL - mounted outside with the camera on it - makes? I'm using the the Ring app I can change the notification sound my PHONE makes, but there is no guidance on how to change the sound the actual hardware makes. Guides on this community page appear to describe a process that is out of date now and does not exist in the Ring app, ie selecting "audio settings", which is not currently in the ring app.
