Because you are new, I just want to make sure that beyond downloading the code, you're Adding them, right? You will go into the Apps menu item on the left and click Add User App
Then find/select the new app and it will then appear in the list of apps. Then you use that to set the IP, etc.
Again, it's not always clear what "install" means when it gets done twice.. one to add the code and then again to make the code active.
If you haven't installed (and made active 
) Hubitat Package Manager (HPM), then I'd suggest you review it for its value. Its purpose is to do all the fetch/download of code.. all the pieces, as one "package". You simply select the name of the Package and finds the code and installs all the apps all the drivers, all the libraries, and so on. You then proceed to using the code, installing it
You may not be familiar with importing code...
use this Import URL:
https://raw.githubusercontent.com/HubitatCommunity/hubitatpackagemanager/main/apps/Package_Manager.groovy
In Apps Code, click Import, paste the URL above and click Import. Then go to Apps and again, use the Add User App and find Hubitat Package Manager.
