I'm attempting to use the Data Management API to update the display name of an item within BIM 360 Docs, it looks like [this API call](https://developer.autodesk.com/en/docs/data/v2/reference/http/projects-project_id-items-item_id-PATCH/) is the one I'm after, however the documentation for it is less than helpful.

I can see the call should be...

developer.api.autodesk.com/data/v1/projects/**PROJECT ID**/items/**ITEM ID**

which makes sense, its the body that is less than descriptive

-d '{ "jsonapi": { "version": "1.0" }, "data": { "type": "items", "id": "*urn:adsk.wipprod:dm.lineage:AeYgDtcTSuqYoyMweWFhhQ*", "attributes": { "displayName": "new name for drawing.dwg" } } }'

Theres no indication as to what the urn is and how i should go about getting it, I've tried just using the item ID again with no joy, if anyone could help me it would be much appreciated,
