Hi there!  
I'd like to have already parsed field **app\_message** additionally parsed with fields like **language,**** companyEmail, ****country ,**

Please suggest the proper way to do this.

```auto
    <filter kubernetes.**>
        #@id filter_parser
        @type parser
        key_name log
        reserve_data true
        reserve_time true
        <parse>
          @type grok
          grok_failure_key grokfailure
          <grok>
            pattern %{TIMESTAMP_ISO8601:app_timestamp}" level\=%{DATA:app_log_level} msg\=%{GREEDYDATA: **app_message** }
          </grok>
        </parse>
    </filter>

```

**app\_message** content:

`Create data draft in db: DatasetDraftVO(id=d57f73fc547f, datasetVO=null, entityId=legalEntityId, datasetVersion=1, data=VerifiableCredential(contexts=[https://www.w3.org/2018/credentials/v1, https://app.com/api/v1], id=le_cd_1, types=[VerifiableCredential,credentialSubject={"corporateData":{"bylaws":{"value":""}," **language**":{"value":"English"}," **legalForm**":{"value":"Private limited company"}," **legalName**":{"value":"CompanyName1"}," **companyEmail**":{"value":"[te...@mail.com](javascript:)"}," **companyWebsite**":{"value":"MyProgram.fr"}," **country**":{"value":"France"}," **mailbox**":{"value":"444"}," **zipCode**":{"value":"2000"}} proofs=null), **draftStatus** =DRAFT)`
