Centred Logo with Navigation on Either Side (Problem with Guide)

Hi,

I want to achieve something similar to this - https://prnt.sc/uqqja5

Center the logo and split primary menu on desktop.

I already followed this guide shared - https://docs.generatepress.com/article/centering-logo-navigation/

But, I am having issue that the menu isn't splitting even after following each step. The logo floats above the primary menu. On mobile, it looks good.

Here's the website - https://potatoblogger.com/

Can you please take a look?

Thank you!
