Singlefile Windows Form Application executable with modern browser embedded possible?

Question

I'm completely new to C# and Visual Studio 2019 but I managed to create a Windows Form App with chromium embedded in it via CefSharp. All I need now is to pack it into a single .exe file. Right now it has a bunch of folders near generated .exe file and it doesn't run without most of them. I looked everywhere but I can't find a tick or an option to compile into single file

Right now I'm stuck with this error I'm trying to do this:
dotnet publish -r win-x64 /p:PublishSingleFile=true /p:IncludeNativeLibrariesForSelfExtract=true --output "D:/temp/"

but get this error multiple times (everywhere where I use cefsharp)
error CS0246: The type or namespace name 'CefSharp' could not be found (are you missing a using directive or an assembly reference?)

It launches and builds fine with a "Run" button but it produces multiple files instead of one.

I'm not entirely sure if that's even possible so I'll ask an another question I guess - how does one go about creating a single file exe with embedded chromium? (Or at least EDGE, WebView defaults to IE7 or at best IE10 which is also not ideal)
