Trying to get functions from the Datasmith Content Blueprint Library from the engine folder, but will not appear

I’m trying to automatically sort models imported from CityEngine using metadata and to do that i need the Get All Objects and Values for Key function, but i cannot add it in the blueprint editor. I’ve tried adding it’s Libray into the project and a verity of other workarounds, but they haven’t worked. I’ve looked through the documentation and havn’t been able to find anything. What can i do?

It is an editor only function so it will not be available in normal blueprints (normal blueprints are expected to work at runtime).
Do you need that function at runtime / in a package application? Else if you can do the sorting in editor then you could use a editor utility widget for example.
