Just to give the full answer.

As mentioned by Simon the DataMiner user rights shown by Alberto are only needed to update existing connectors through DCP, it does not apply for deploying new connectors from the catalog.

No DataMiner permissions are necessary for a user to be able to deploy a connector to a specific system. The users needs to be added to the system on dataminer.services (which you can do in the DCP Admin App, procedure described in the docs here).

Hope this fully answers your question, if not feel free to get in touch.
