At the end of the file, add below section:

    {
        "name": "locked-fields",
        "data": {
            "participant": {
              "<External data source name>": [
                  "cpr.participant.firstName",
                  "cpr.participant.lastName",
                  "cpr.participant.middleName",
                  "cpr.participant.birthDate",
                  "cpr.participant.gender",
