Siren Investigate Configuration for 2 node cluster ES servers

Hi Team,

I am installing Siren Investigate on a node which is not a master and nor the data node but in cluster with other node which is master as well as data node.

1st node - Coordinating node
2nd node - Master /Data node

I need to confirm do i need to confirm which node url i need to use in the configuration file investigate.yml apart from it any other setting need to do for it?

Thanks
