Only one index data visible in Dashboard

Hi,
I am trying the opensearch stack for my project and facing issues with opensearch has multiple indices such as logstash, system-logs etc. on the opensearch dashboard, only one index, logstash is visible, others are not. Also there is no evident ways to add new indices to teh dashboard.

Please guide about it.

Thanks,
Prasanna

I got the option to add new index pattern under “Stack Management”.
