Retrieving Linkedin DSC Name via API

Question

I'm trying to retrieve the "DSC Name" of creatives via the Linkedin API. These are included in the performance report exportable through the Linkedin campaign manager but I can't find any reference to this field in the API documentation.

I can retrieve creatives no problem through the adCreativesV2/<creative_id> endpoint and I've tried some projections there as well but nothing seems to return that field.
