StandaloneFileBrowser for MacOSX

Hi,
I'm trying to build for MacOS IL2CPP for FileBrowser plugin but can't get it to work. Works fine on macos and standalone mono and editor.

I get this in failed il2cpp log file:
System.Windows.Forms.dll assembly is referenced by user code, but is not supported on StandaloneOSX platform. Various failures might follow.

How do I use the StandaloneFileBrowser file in subfolder StandaloneFileBrowser.Bundle/Contents/MacOS ?

Dlls Ookii.Dialogs, StandaloneFileBrowser, System.Windows.Forms have the option to include Editor, Standalone or WSAPlayer but not MacOS?

Also I notice the plugin folder for this asset is inside the StandaloneFileBrowser directory (StandaloneFileBrowser/plugins), should I move all/part of these dlls or this plugin folder into the Assets/plugin path?

Sorry, I find this quite confusing, please help

Thanks a bunch, Sergio
