Extension can't connect to VPL in Moodle

Hey, first of all, thanks for creating this extension.

Maybe I'm just not doing it right, but I can't manage to connect my VSCode to VPLs on Moodle. I give the extensions the URL to the VPL, it adds it to the json file, but I can't see the files that I need to edit.

Do you have any ideas, what the issue is?

Thanks, Tjorben
