Dude, you expected this app to just detect everything in your room and create all of the boundaries for you? It even tells you how to set it up on the app page. Not the dev's fault you don't want to read, or have poor reading comprehension..
This app is awesome, and the setup is not that difficult. Maybe you should just stick to the Oculus store and avoid App Lab/Sidequest apps? Doesn't seem like you're ready for these, yet.
