How to list previously approved apps from "Filter Network Content" pop-ups? It appears that when an application needs to filter or monitor network content MacOS asks the user for approval.
How can I check (either GUI or command-line) which applications have been approved before?

systemextensionsctl list

This lists all system extensions. The usage mentions a category can be given to filter the list but the manual doesn't document what categories can be provided.
