Find all process model UUID of an Application by plugin

Hi,

I am working on Appian 18.4 server.
I am looking for a way to get all Process Model folders and Process Models associated with an Application via plugin.

In Appian API I see a class com.appiancorp.suiteapi.applications.Application.AssociatedObjects which has a method getGlobalIdMap() which returns com.appiancorp.ix.GlobalIdMap type.

I believe com.appiancorp.ix.GlobalIdMap would help me to dig further. Unfortunately in Appian 18.4 SDK we don't have com.appiancorp.ix.GlobalIdMap class. Also I could not find the same class in API Documentation.

I am stuck here. Can anyone help me on this?

Thanks!
