Which service user is used for AEM and Adobe IO

Hi All,

I am trying to send events from AEM to Adobe IO, I am following below documents which results in steps below

https://developer.adobe.com/events/docs/guides/using/aem/aem_skyline_install/

To install and configure the Adobe I/O Events package on AEM as a Cloud Service:

1. Set up your workspace in the Adobe Developer Console
   • Prepare your JWT Authentication public/private keys
2. Use Cloud Manager environment variables to power your OSGI configuration.
3. Optionally do some more configuration fine tuning.
4. Deploy these osgi configurations, together with aem-aio-events package using Cloud Manager. You may refer to this working sample aio-aem-events-sample.
5. Trigger aem-aio-events package status check endpoint

As part of JWT auth I am following the below documentation to set public private keys

https://experienceleague.adobe.com/docs/experience-manager-learn/foundation/authentication/set-up-public-private-keys-for-use-with-aem-and-adobe-io.html?lang=en

My question is for which service user should i configure keystore to.

I tried it configuring for aio_service_user which I assume was created by 

https://github.com/adobe/aio-lib-java/tree/main/aem/aio_aem_events 

Thanks,

Shehjad
