Access Bluetooth in system daemon - Unauthorized

Hello, as the title says, I am trying to access Bluetooth in a system daemon. I am running on MacOS Sonoma 14.5. When initializing Bluetooth, my daemon received Unauthorized state. I have tried to add my daemon in the system settings (System Preferences > Security & Privacy > Privacy > Bluetooth) "Allow applications to access Bluetooth" by adding the program executable path defined by the entry Program of my system daemon as suggested here: https://developer.apple.com/forums/thread/662459. But I am still having the issue.

Writing a system daemon with Bluetooth is not my final goal. The bigger picture is the smartcard reader driver with Bluetooth access which as the same issue and the solution is probably related. I do not remember how but my smartcard reader driver use to work with Bluetooth but it does now with the same Unauthorized error.

As far as I can see daemon and smartcard drivers does not have support for entitlement.

Here are the logs for my sample system daemon:
