Hello,
At the moment, we have onClick functionality on the “Sticky navigation” element itself from the header: https://gyazo.com/a82e6844c0a199bb38b1907031bc51c8

Unfortunately, there is no option in Theme Settings to open it by clicking on the navigation panel itself: https://prnt.sc/0HsctkbOyA15
Kind Regards
