Niagara Neighbor Grid not showing an option ot Initialize

I’m currently trying to create some Boids for a science exhibit, and I’m working with the example in the ContextExamples.

However, in my other project, I’m trying to initialize a Neighbor Grid3d. There doesn’t appear to be an option to initialize a Neighbor Grid.
There’s an option to set a neighbor grid parameter, however there’s no Initialization options.

Am I looking in the wrong place?

In emitter window, find “Parameters” window, then “Emitter Attribute”, click “+”, then search in popup window.
