User Profile

I got the approval to use the DriverKit entitlement last week. since then I am trying to generate a profile with this entitlement without any success. I do not see the 'additionnal entitlements' dropdown in the profile creation wizard.I am certainliy missing something somewhere, but what ? bundle id is a mac app bundle id with no particular capability selected. I thing 'system extension' is to use with the host app and not the dext. Is there any dependency to take into account ?Any advice ? thanks
