How to Know When a Device is Provisioned with Greengrass

Hey everyone,

Providing a bit of context: we utilize a custom Debian package for device provisioning, and distributing it to customers. This package incorporates essential device certificates and configurations, and upon installation, triggers the Greengrass systemctl service. Our goal is to identify when the customer executes the Debian package so that we can take specific actions on our EKS services accordingly.

How can we ascertain whether a device has been provisioned with Greengrass? Are there any MQTT topics or triggers that are activated once during the provisioning process?

Thanks
