Style Search Bar in Navigation 7.1

Site URL: https://www.gypset.com/

Hi, I recently added the search bar to my header using this code https://www.will-myers.com/articles/adding-a-search-bar-to-your-header-in-squarespace-71

Is there any way to customize it so I can remove the search box and background, make the icon and text pink and smaller, I want to make it match my site a bit more. Im excited about getting the feature there but I want it look good. i would love it to look like the screenshot attached but it might be too much to ask! Im just happy to style it so it looks like it belongs.

Thanks in advance
