Bulk Import of Cases with Action Plans

Summary:

We are currently working on a data migration requirement involving Cases and their associated Action Plans.

We have successfully successfully mapped and tested the migration of the parent Case records using the standard Import Management tool. However, we are facing a blocker regarding the child records: Action Plans. Upon reviewing the list of available Import Objects, I cannot locate a specific object for 'Action Plans,' nor do I see them exposed as a child attribute within the Case object.

Has anyone successfully migrated Action Plans previously? I would appreciate any insights on whether this is supported via Import Management.
