GraphQL : `_contained_in` syntax for search matching key and value pair from jsob field

Unable to create Query for _contained_in using Hasura Graphql

_contains Query

query MyQuery($data_rule_list: jsonb) {
  mbr_pgm(where: {nom_org_id: {_eq: "XXX"}, data_rule_list: {_contains: $data_rule_list}}) {
    data_rule_list
    key_wrd_txt
    updt_ver_nbr
  }
}

Variable :

{
  "data_rule_list": {
    "offerNumber": "0196819"
  }
}

Facing Issue to Create _contained_in query

If Query for _contained_in is :

query MyQuery($data_rule_list: jsonb) {
  mbr_pgm(where: {nom_org_id: {_eq: "XXX"}, data_rule_list: {_contained_in: $data_rule_list}}) {
    data_rule_list
    key_wrd_txt
    updt_ver_nbr
  }
}

What should be the Variables ?

I Tried. Not Working

{
  "data_rule_list": {
    "value": [
      {
        "offerNumber": "0196819"
      },
      {
        "offerNumber": "0196820"
      }
    ]
  }
}
