I am trying to update the 'Credits' property (feature services and views) using arcgis api for python and I have had no luck. I've tried 'update' on the item and 'update_definition' on the flc and I don't see a 'credits' property. Can someone explain who this is done? I can do rudimentary jupyter notebooking, but haven't been able to find the correct property.

Thank you,
Randy McGregor
