Thanks. I tried messing with the zIndex but it didn't work. It seems like the invisible toolbar background is always above the detail view, even if the zIndex is .infinity

.toolbar is not an option for a couple of reasons: I find it very difficult to control grouping and layout of Toolbar Items I also need a bottom toolbar, and I would like both toolbars to share the same look & feel. Since there is not bottom toolbar option on the Mac, I end up with a Liquid Glass toolbar at the top and a regular toolbar at the bottom. In short, I'd like to control the layout and look of both toolbars and the built-in SwiftUI toolbar is not flexible enough for this.

Thanks. This still doesn't work in macOS. For the button to be flush to the top I still need the .ignoresSafeArea modifier, and then the button is not clickable like before. Even if it worked, I need it to work in macOS 15+, not just Tahoe, and safeAreaBar is only available in os26 and above.
