How do I update my NPI profile??

Hey guys! Brand new BCBA, passed Wednesday, still can’t believe it’s happened finally. Now I’m doing all the joyous licensing stuff so I can work, but I seem to have run into a roadblock-

How do I change my NPI profile info to say I’m a BCBA? Do I need to call them? I’ve navigated to the taxonomy page, but it’s saying I have “read only” access. Do I need to call? Google keeps saying I should be able to do it on my own.
