In VS Code you should have an explorer pane to the left.
There should be a section called root and under that one called config (I have two configs for some strange reason, but in the “wrong” config, the right config is located inside???)
EDIT: Ahh, one of them have a tiny dot in front of the name
Just choose the first text under the explorer in the left pane.
It should be the file browser and it should either open up in root or directly in config.
