 2. Register the action in the [OpenSearch Security plugin](https://github.com/opensearch-project/security). Each new action is registered in the plugin as a new permission. Usually, plugins will define different roles for their plugin (e.g., read-only access, write access). Each role will contain a set of permissions. An example of adding a new permission to the `anomaly_read_access` role for the [Anomaly Detection plugin](https://github.com/opensearch-project/anomaly-detection) can be found in [this PR](https://github.com/opensearch-project/security/pull/997/files).
 3. Register the action in the [OpenSearch Dashboards Security plugin](https://github.com/opensearch-project/security-dashboards-plugin). This plugin maintains the full list of possible permissions, so users can see all of them when creating new roles or searching permissions via Dashboards. An example of adding different permissions can be found in [this PR](https://github.com/opensearch-project/security-dashboards-plugin/pull/689/files).
