Ability to enable hand gesture instead of button press for door bells to fight covid-19

Currently there's no way to detect hand gesture and ring the bell. Always visitors have to press door bell button. It'll be great to have detect ✋ palm gesture and do the ring, would help stop spread covid-19 too. Users would be able to enable this feature optionally. Ring could add a sticker for future product shipments, so people could add it on door bell devices. Cheers, Pasan
