Blueprint to get Renderpasses of Post Process Lighting Components

Hi! I hope i am not wrong here as a beginner but i just found two posts regarding my question and none was a solutuin for me. I am trying to render the Lighting Components in the Post Process Volume. I am using the Path Tracer and for that i need to create a blueprint:

https://dev.epicgames.com/documentation/en-us/unreal-engine/path-tracer-in-unreal-engine?application_version=5.3#renderinglightingcomponentswithmrq

I found this tutorial and i am struggeling to replicate that. There is just a picture and no real explanation how to set that up. I cannot find that PPV AOV. I managed to get the Set node but it wont connect to my “make post process Settings”. Its my first time in those blueprints so i am kinda lost here.

Would appreciate any help. Thank you!
