How to build Safety Island Actuation demo for a different cluster?

Hi,

I am deploying the ARM Kronos reference software design on my own hardware. This is the demo I'm trying to reproduce:
https://arm-auto-solutions.docs.arm.com/en/v1.1/user_guide/reproduce.html#user-guide-reproduce-actuation-demo

By default, the 'actuation service' runs on Safety Island cluster 2. I want to run it on cluster 1. What modifications do I need to build the demo for primary-compute-to-safety-island-cluster1 communication instead of primary-compute-to-safety-island-cluster2 communication?

Regards,
