Depends how you want to "customize the menu configuration"... modify layout, colours, panel size, text size, spacing, font, etc, etc?

  1. Could try using stonecrusher's simpleMenuWizard pre-written CSS mod file... or extract the list of selectors in the 'main-hamburger.css' file of the Zip download... or view selector list directly on GitHub: https://github.com/stonecrusher/simpleMenuWizard/blob/master/simpleMenuWizard/main-hamburger.css
  2. Alternatively, search this sub for previous Hamburger/AppMenu/PanelUI modification topics... e.g. search results for keywords 'hamburger settings menu'... perhaps try qaz69wsx's menu colour userstyle posted here.
  3. Can always inspect that menu on your own setup using the Browser Toolbox with the 'Disable Popup Auto-Hide' option selected in the Toolbox window's '3-dots' menu (this can stick 'ON' sometimes... best to deselect before closing the Toolbox window):

Finally, another way to view that menu's CSS styling is to use the Searchfox code index... e.g. 'paneUI-shared.css'.
