Ring Alarm Manager not showing up on list of Smartapps in new ST app

[rvs007]

I just bought a Ring Alarm system and since I have SmartThings set up for my home automation and most of my devices installed on ST, I thought I'd try integrating the Ring Alarm into ST using this implementation. I know the author has moved away from ST to Hubitat but is the latest V3 working on ST? I've gone through all the sets in setting up on AWS and getting the API, installing the device handler & smartapp. However, the Smartapp isn't showing up on my list under Automation after installing & publishing in the IDE. Anyone successfully added the Ring Alarm into ST recently (in 2022)? I see issues raised in 2020 but nothing more recent.

This integration stopped working for me over a year ago and I haven’t tried it since. I’ve given up on it and just use the two apps separately. I’ve also found that the Alexa integration does everything I would need the ST integration to do.
