Recording audio in keyboard extension

How can I record audio in a keyboard extension? I've enabled microphone support by enabling "RequestsOpenAccess". When I try to record, I get the error below in the console. This doesn't make sense as Apple's docs seem to say that microphone access is allowed with Full Keyboard Access. What is the point of enabling the microphone if the app cannot access the data from the microphone?

-CMSUtilities- CMSUtility_IsAllowedToStartRecording: Client sid:0x2205e, XXXXX(17965), 'prim' with PID 17965 was NOT allowed to start recording because it is an extension and doesn't have entitlements to record audio.
