Ask button > Assistant not discoverable enough

[denisemcg]

My Customer Success team just shared excellent feedback about the Ask > GitBook Assistant. They use it all the time now to get concise answers when responding to customers. :)
However, some say that they didn't know about it - they thought the Ask button was a label describing the search box.
Can you make this great feature more discoverable. Or allow us to customize the look/size/color/location of the Ask button.
Currently my primary button is the most noticeable things on the top bar, but now I think the Ask should be.
