In another question on this forum (https://developer.apple.com/forums/thread/124775) eskimo stated that launching a system extension from an daemon is not the right approach and that the OSSystemExtensionRequest.activationRequest API should be called from an App.
My question is, does this same restriction apply to a LaunchAgent started App?
If so, to ensure activation as soon as possible is the only option to use a SMLoginItemSetEnabled helper to start the App on login?

Yes, do not activate a System Extension from a daemon, launch agent, command line tool, helper app, or any other mechanism other than the Container App for the extension. Doing so may cause issues and inconsistencies when deactivating and uninstalling.
Also, a Network System Extension on macOS is started when the system starts so you should not need to worry about starting the extension as soon as possible. Last I knew, networking on the system was not allowed until the Network System Extension was started.

Thanks for the clarification, Matt.
If our app is installed or updated without a user login active, ie via MDM like JAMF, how should we ensure the Container App is run on login so that the system extension activation or update (ie .replace) is performed?
I'm trying to use a Helper application installed using SMLoginItemSetEnabled but it's not starting the App. However, will that even work from a MDM install?

Are you able to run an open command from a post install script on startup to make sure your container app is opened to complete the installation / activation flow?

Can my launch agent be the Container App for the system extension? Or does it need to be separate?
Can my launch agent be the Container App for the system extension?
See here for my standard advice on that topic.
