@noemi, is your hamburger menu showing on desktop? If the hamburger menu is only visible on tablet/mobile view then your only option is to have it visible with a tap/click since hover relies on a mouse to work.
Thanks for URL.
navigation menu and toggle menu code are total diffrecnt so i can be done some modication code on backend size.
It can be done by doing some code customization. please send me a personal message and we can discuss what you'd like
