How to add Ring (or anything else0 to the new app

I had a doorbell die and now it doesn’t seem to be working in SmartThings. I haven’t had a lot of time to troubleshoot, but my thought was to quickly remove the Ring integration completely and add it back in. Before I did that, I wanted to know how to add it back.

So, I currently have Ring in Settings → Linked Services and can see how to delete it. But, I can’t seem to find anything letting me add services in that menu.

Can someone point me in the right direction?

You have to add a new device that has a linked service, in this case Ring, when you choose the type of device it will ask you for the data to link your ring account to smartthings
