+Since no one has volunteered to take on the role of release owner for this component, we are randomly selecting you to be the release owner. </br>
+If you feel this should be reassigned, please feel free to delegate it to the appropriate maintainer. </br>

+Hi ${LIST_OF_MAINTAINERS}, </br>
+
+Could someone kindly volunteer to take on the role of release owner for this component in order to meet the [entrance criteria](https://github.com/opensearch-project/.github/blob/main/RELEASING.md#entrance-criteria-to-start-release-window) ? </br>
+If no one is able to take it on, we may need to assign someone randomly before the release window opens. </br>
+
+Thanks in advance for your help!
