Windows system log Analysis using Security Analytics feature

Can anyone help me to understand how I can I use windows logs in Security Analytics features.

Can you help me with the steps.
I have an agent which collects windows event logs and sends it to Opensearch.

Also provide detail on how to generate alerts and how these mapping work internally.
Kindly advise.

@tallyoh I see one of the forum post and it seems like you have some idea around it, it would be really helpful if you can give some advice around it.
