Everything on the left hand side is already implemented in JC. "File Servers" for example can be configured with the help of this documentation.

I needed a way to refresh the titles (inventory data) which can be handled via the jamfconnect://update. I added the networkcheck as well as it felt natural to refresh "everything"

The Endpoint Manager section is dynamic. It shows only a register button if the integration has not been set up and sends notifications. "Send inventory" and "Check compliance" are only visible when the registration already occurred. Its part of our onboarding process to register the Intune integration via JC as we do not use the Self Service :)
