@christophetd thoughts on this? Would it be worth modelling it after one of these? https://stratus-red-team.cloud/attack-techniques/AWS/aws.discovery.ec2-enumerate-from-instance/ https://stratus-red-team.cloud/attack-techniques/AWS/aws.execution.ssm-start-session/

Absolutely, I think it makes sense to implement it like aws.execution.ssm-start-session
