Persons V2 Api doesn't provide Org Unit IDs

Organizational entities (Org units, Offices, LEs, Cost centers) are transferred with their id only. Names can be retrieved using the v1 API or the Org unit endpoint

Is displayed at the top. Currently we are using the V1 API but would like to move everything over to V2.

The message hints that OU IDs are transmitted in the V2 Persons API, but it's not.

How could we get the IDs attached to each Employee?
