Godot Version
4.2
Question
I’ve made an EditorNode3DGizmoPlugin in GDScript by following the tutorial in the official docs. This gizmo seems to be working great, but I don’t know how to trigger it to redraw using GDExtension and godot-cpp.
This gizmo operates on a Node3D type that I created using godot-cpp and GDExtension. This custom C++ node has internal data that changes from time to time. Whenever this data changes, a _redraw should be triggered on the gizmo that’s attached to it.
How do I go about triggering this redraw in C++ with godot-cpp?
