You can also use the REST API as an alternative for provisioning by running the following command:
curl 'https://api.provisioning.nrfcloud.com/v1/claimed-devices' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer YOUR_API_TOKEN' \
-d '{"claimToken": "YOUR_DEVICE_ATTESTATION_TOKEN", "tags": ["nrf-cloud-onboarding"]}'
