Owner of shared folder with V2 API

I'm having a hard time trying to figure out the owner of a shared folder. Our business app has the 'Team member file access' permission.

The /list_folder API, returns the parent_shared_folder_id in this form,

"parent_shared_folder_id": "dbsfid:AACaAsPOBxY9rbpj6-y635yDW0_GjuKM9c0",

I'm trying to figure out the owner of this folder. The v2 get_metadata, and get_folder_metadata does not return who the owner is. 

 

The v1 /delta API returns the shared_folder_id in the following form

"parent_shared_folder_id": "1062669200"

With this ID, I can perform https://api.dropboxapi.com/1/shared_folders/<id> and get the owner. But we want use the V2 API's because of file ID's.

Is there any solution?

Thanks,
