mobile menu trap focus and/or escape to close overlay menu

Hey, I think I replied to my old post about this — https://kriesi.at/support/topic/mobile-menu-trap-focus/ — but I’m afraid since that topic’s closed my reply may have been lost in space ;) More of my clients are wanting improvements in accessibility these days, and the mobile menu seems to be a key issue. Have y’all looked into trapping the focus (when tabbing through the site) in the mobile menu so it cycles back to the close X link instead of carrying on to the site behind the overlay? Ideally, the user could also hit escape at any time to close the menu/overlay. Any chance of adding this functionality/accessibility somehow? This is one of the sites I currently need it for: https://tortoise-tracks.org/ — thanks and lmk if you have questions.
