Trying to Make an Editor Script that Needs to Find All JSON Files in a folder, File Utils Nodes Missing

Hi, so I want to make an blueprint editor script that reads through and process all JSON files in a given directory. Unreal documentation seems to show many useful nodes, but when I actually try to find the nodes in the search bar when editing an event graph, they simply do not show up. I am using UE4.26

Here are links to a couple of the nodes that I want to use but my event graph does not show: FindFiles and FindRecursive.

Nevermind, I found the solution. File Utils just needs to be added as a Plugin to use those nodes.
