VCACAppServices:Deployment (vRA 7 multi machine) - how to get children?

Hi

I understand in 7 the new canvas now creates "deployments" (or VCACAppServices:Deployment)

what should i pun in a vro workflow to get the VCACAppServices:Deployment and get the children of this deployment ?

is there any example / documentation anywhere ?

the idea is to run a day-2 action on the multi machine

Thanks !
