Having trouble finding the proper key for multiple settings on Elasticsearch 7.1.1. The documentation seems to be trying too hard to not be repetitive or assume a certain level of knowledge that I don't have.

```auto
xpack.security.authc.realms.type: native
xpack.security.authc.realms.native.authentication.enabled: true
xpack.security.authc.realms.native.cache.hash_algo: "pbkdf2_1000"

```

I get the following error

```auto
Caused by: org.elasticsearch.common.settings.SettingsException: Failed to get setting group for [xpack.security.authc.realms.] setting prefix and setting [xpack
.security.authc.realms.type] because of a missing '.'

```
