Hey @rishabh6788 @gaiksaya, thanks for the review! Derek just updated the PR to remove the todo. Let me know if you think it's good to merge - I saw a build failure though. But looks like a non-related one

Hi @derek-ho @ansjcy

Can you also please add the plugins to the test manifests?
Example 2.19.0: https://github.com/opensearch-project/opensearch-build/blob/main/manifests/2.19.0/opensearch-dashboards-2.19.0-test.yml and similarly to 3.0.0 test manifest as well?
Thanks!
