I would like to say that the Integration between smartthings and Ring that Ring has most responsibility to do this unless you don’t want to.
Smarttthing is a platform. They provided the API and developer guide for third-party to do the integration. The only thing smartthings will do is to approve or deny the integration based on the technical requirements.
So if the products is not able to integrate with Smartthings, Ring is the one who should be taking care of instaed of referring to smartthings team directly
