Custom signals as C# events (Godot not generating events from the Event Handlers)

Godot Engine v4.1.1 / using VSCode

C# events apparently not generated when writing signals in C# as defined by the documentation. Maybe they are behind the scenes somewhere, as the if I try to make my own events with the name, Godot will complain, however I can't seen to access the events through the API. The documentation implies that after settings up the delegates and building in the editor the events should just appear in the API, but they do not. The signals I made appear find in the editor.
