I'm using node.js Elasticsearch 7.17 client to create default index settings, and I'd like the total_fields limit to be more than the default 1000. When I try the following:

export const defaultCaseIndexSettings: IndicesIndexSettings = {
  'index.number_of_replicas': 0,
  'index.number_of_shards': 6,
  'index.max_result_window': Number(INDEX_MAX_RESULT_WINDOW),
  'index.mapping.total_fields.limit': 10000,
etc.
}

it seems that index.mapping.total_fields.limit is not a setting that can be set on IndicesIndexSettings. I've also tried:

export const defaultCaseSettingsIndexConfig: IndicesCreateRequest['body'] = {
  settings: {
    index: {
      number_of_shards: '2',
      number_of_replicas: '2',
      mapping: {
        total_fields: {
          limit: 10000,
        },
      },
    },
  },

and that gives me the message that Object literal may only specify known properties, and 'mapping' does not exist in type 'IndicesIndexSettings'. How can I set the total_fields limit using nodejs Elasticsearch client?
