How to use Mica and Acrylic for a Win32 on Windows 11

How to use Mica and Acrylic for a Win32 (WPF for example) app on Windows 11 ?
I know that MS Edge Dev did it (for the titlebar and Flyout menus).
Maybe the new DWMWINDOWATTRIBUTE DWMWA_USE_HOSTBACKDROPBRUSH is the key.
So if true, WinUI 3 acrylic microsoft/microsoft-ui-xaml#2236 issue can be easily resolved for Windows 11 (but continues to be an issue for backward compatibility).
