How can I get the "root" directory inside a ScopeProvider?

[AignerGames]

Hallo, I implement a custom ScopeProvider which uses the DefaultScopeProvider as a base and override the getGlobalScope with custom logic. I need a way to get the current "root" directory of the files (when they are edited inside VS Code), but I can't find any API to get this information. I tried to google and asked some chat bots, but they all gave me answers with an outdated API.

I have access to the LangiumCoreServices, which has access to TextDocumentProvider, WorkspaceManager, FileSystemProvider, LangiumDocuments and many other things but I checked all of them and couldn't find any functions which would give me the root directory.

Additional info:
By default the scope provider returns all elements from all files, but I want to restrict this and only return elements from the current file and elements from files which are located in the directory root/Global, that's why I have to know the root directory to find the directory named "Global", as a workaround I currently only check the directory name, so the directory can be nested anywhere and there can also be multiple. It's only a hobby project so it doesn't matter too much and maybe it's even a good feature to allow multiple "Global" folders, but I was still interessted to know if there would be a way to get the root directory.

maybe calling serivces.shared.workspace.WorkspaceManager.workspaceFolders() does the trick

Yes, exactly. You should be able to use the WorkspaceManager#workspaceFolders getter together with the uri of the current document to find out what the current workspace folder is.

Thanks for the answer, it looks like I have a old version (3.2 instead of the current 3.3), because my version doesn't have the workspaceFolders. I will try it again once I manage to update the langium version. (Im new to TypeScript and VSCode node development and I get a timeout error everytime I try to update, but I will try it again after the holidays)
