MacOS - AppKit + SwiftUI - Liquid Glass Without Any Blur

I've been trying to set up liquid glass effect like on screenshot below and can't figure out how to do it. Tried official documentation methods even with .glassEffect(.clear) but got nothing.

-> swift --version

swift-driver version: 1.127.14.1 Apple Swift version 6.2 (swiftlang-6.2.0.19.9 clang-1700.3.19.1)
Target: arm64-apple-macosx26.0

-> sw_vers

ProductName:            macOS
ProductVersion:         26.0.1
BuildVersion:           25A362

what I want

I'm using AppKit to set up my window and NSHostingView to host SwiftUI.

what I've got

Here's the code.

window setup:

    @MainActor
    private func setupWindow() {
        let barHeight: CGFloat = 35
        let barHorizontalCut: CGFloat = 10
        let barVerticalCut: CGFloat = 2
        guard let mainScreen = NSScreen.main else { return }
        let screenFrame = mainScreen.frame
        let frame = NSRect(
            x: barHorizontalCut,
            y: screenFrame.height - barHeight - barVerticalCut,
            width: screenFrame.width - barHorizontalCut * 2,
            height: barHeight - barVerticalCut
        )

        window = BarWindow(
            contentRect: frame,
            styleMask: [.borderless],
            backing: .buffered,
            defer: false
        )
        window.isOpaque = false
        window.backgroundColor = .clear
        window.level = NSWindow.Level(rawValue: NSWindow.Level.statusBar.rawValue - 1)
        window.ignoresMouseEvents = false
        window.collectionBehavior = [.canJoinAllSpaces, .stationary, .ignoresCycle]
        window.hasShadow = false
        window.orderBack(nil)

        let container = NSView(frame: frame)
        container.wantsLayer = true
        container.layer?.backgroundColor = .clear
        // ensure container's layer is not opaque so alpha can show through
        container.layer?.isOpaque = false
        container.layer?.cornerRadius = 16
        container.layer?.masksToBounds = true

        // Host a SwiftUI view inside AppKit
        let hostingView = NSHostingView(rootView: BarContentView()
                                            .frame(maxWidth: .infinity, maxHeight: .infinity))
                            
        hostingView.translatesAutoresizingMaskIntoConstraints = false
        container.addSubview(hostingView)

        // Constrain hosting view to container
        NSLayoutConstraint.activate([
            hostingView.leadingAnchor.constraint(equalTo: container.leadingAnchor),
            hostingView.trailingAnchor.constraint(equalTo: container.trailingAnchor),
            hostingView.topAnchor.constraint(equalTo: container.topAnchor),
            hostingView.bottomAnchor.constraint(equalTo: container.bottomAnchor)
        ])

        window.contentView = container
        window.makeKeyAndOrderFront(nil)
    }

widget setup:

        // deleted unnecessary code
            HStack(spacing: 0) {
                HStack(spacing: 8) {
                    timeButton(width: timeButtonWidth, height: widgetHeight, cornerRadius: cornerRadius)
                }
            }
        }


    func timeButton(width: CGFloat, height: CGFloat, cornerRadius: CGFloat) -> some View {
        TimelineView(.periodic(from: .now, by: 1.0)) { timeline in
            Button(action: {
                let url = URL(fileURLWithPath: "/System/Applications/Calendar.app")
                NSWorkspace.shared.open(url)
            }) {
                HStack(spacing: 4) {
                    Image(systemName: "calendar")
                        .foregroundColor(.white)
                        .background(.clear)
                        .font(.system(size: 12))
                    Text(timeline.date.formatted(date: .abbreviated, time: .standard))
                        .foregroundColor(.white)
                        .background(.clear)
                        .font(.system(size: 12))
                }
                .frame(width: width, height: height)
                .glassEffect(.clear)
            }
            .frame(width: width, height: height)
            .cornerRadius(cornerRadius)
        }
    }
