There should be no other step.

The device should discover DNAC (using Option 43 or DNS).

The device will move into the provisioned state under PnP, and as a part of that process be discovered.

The only thing i can suggest is you do not have the correct credentials configured under the network settings? Design -> NetworkSettings -> Device Credentials. You need to have a valid privilege 15 username and password as well as SNMP RO
