I developed an app including driver extension. So I tried to distribute it to users. Of course, it works fine in my Mac. I pressed "direct distribution" through the distribution menu in xcode, but the error occurred as below. I also checked that distribution are fine with TestFlight(internally), checked unregistered mac device. I can't figure out what's wrong, so I'm asking for help. Thank you.

Hello everyone! I'm developing framework and app for macOS for PCI devices. For communication with driverkit, I'm verifying by giving userclient access entities of system extension to app. However, the app is just a sample program, and our customer is trying to develop the app using a framework with PCI communication part. Is there a way to build a framework with my company's signature, and to build and execute it without acquiring userclient access elements by any chance by a customer developer? Moreover, userclient access is only available to developers who have subscribed to the Apple Developer Program, so I hope that client/developers do not need to obtain separate entries.
