Sorry, I'm not sure where else to ask?

I am simply trying to use or test or run this 'GRASP' in any way, I have had no luck after months of coming back and trying repeatedly. I have Valve Index and Oculus CV1.
I found and downloaded the VictoryBPPlugins for 4.19-4.24, I feel like I installed them properly (ie dragged them into projects Plugin folder?)
I can load the 'UnrealGrasp-Master' (It asks for a PAID Plugin called PivotTool, I am sans budget and so would like to avoid that purchase or at leas know this works at all, before I do,).

So far I only see the free standard Unreal Starter Content as the opening Map, and there are no other new maps in the 'master' "branch" ?? … there seems to be no way to do what is in the amazing videos!!! PLEASE What am I missing to find a working version of this? (I see a few blueprints but they are not in any map to illustrate use) I usually learn FROM the project files, they are somewhat self explanatory (when you load them, and they do what they do,..) using whatever opening map the creator had set,
BUT There seems to be no map here with any 'Grasp stuff'... Alsdo when running in VR Preview, no way to move, no hands ,. nothing,. just a table and chairs,.

I'm so depressed I can't just load, run and make this work like every other .uproject I've encountered... Is there any step by step how to simply try this project at its most basic functional level? How to do what it does in the video? I can figure out the rest, how to use it, if I can just get it to run/act/grasp once!
I'm embarrassed to have to ask, this is the very first thing on GitHub for Unreal I could not figure out on my own,.
I still suspect it is me and I am missing something obvious but PLEASE DO HELP, This is too cool and I could really use a win this day,... BUT with no "scene" and o "assets" what is this really? Something accessible only to coders and NOT ARTISTS the people who will SAVE VR in the end,.

PLEASE TRY TO MAKE THIS MORE ACCESSIBLE!!! Why are there 'rights issues' using UE4 free assets? etc? Why can't it just be an example with the Mannequin hands like everything else out there? I have never seen a uproject there that loads to NOTHING but the free UE4 Starter Content! and there is NO DOCUMENTATION that I can find!! PLEASE HELP!!
