NEWBIE: How do I rebind TAB to corfu-complete?

I’m trying to bind TAB to the corfu-complete function, with the following at the end of my config.el:

(map! :after corfu
      :map corfu-map
      "TAB" #'corfu-complete
      [tab] #'corfu-complete)

Right now, in the corfu popup window, TAB cycles forward, and S-TAB cycles backwards. I’m having a lot of trouble understanding how to un-bind TAB from this cycling functionality, though.

I’m sure I’m missing something super obvious, and would appreciate any advice or assistance!
