It didn't work for me, but I found a different solution with custom code.
Another thing I'm still unable to change is that it's always possible to scroll, even when the burger menu is active. I guess if the menu has a solid color, it’s not noticeable, but the moment the opacity of the menu is adjusted or a blur effect is used, I find it very distracting that the content below the menu is still scrollable.
Is there a solution to prevent this?
