I am implementing a C# WinForm application (.net8) that adds a text to the whole screen as a transparent overly (topmost) without interfering with user’s clicks; which I achieved.

But what I am struggling with is that I want it to be displayed over the Windows 11 level UI (e.g.: Win+Tab, Alt+Tab) as well.

I tried to listen to Windows Hooks and ran the Application with Administration privileges but it did not work. I followed this answer as well
