[HOW-TO] Using the Z-Wave Association Tool in SmartThings

I have installed both parts of the App from the links above in SmartThings IDE “My Smart Apps”, however the app never shows up in my Smarthings app (classic or the new one). It should be under Automation/Smart Apps. I have installed, uninstalled, installed again over the last two days multiple times but the app never shows up. I could use some help. Other apps (WebCoRe) i have installed this way have worked.
