Looking for help to apply DependenTree

I’m completely new to this type of development and I’m having trouble figuring out how to apply these examples into the hello-framework and NOT using notebooks. I want to use DependenTree, but I can’t even to seem to get their example running in hello-framework.

Could someone provide some additional steps on how to accomplish this? or 1:1 guidance?

Solved it. Had to look at the Git Issues, another user was having the same issues and provided a solution.
