Cant customize content credentials when exporting from Firefly in the way that is possible from PS?

How do we customize content credentials when exporting from Firefly in the way that is possible from Photoshop (name, social handles, etc)? I am uploading images to LinkedIn. They display "CR" icon but only adobe info is in there, not my "personal creator credentials". I am a subscriber to the full CC suite. Is this possible to do somehow? doesnt seem to be an option in Firefly although it is clearly text-to-image generated by my account and my own style references.
