Question
When we use scene inherit, the default root (node) type of inherited scene is same as base scene. And if we attach or extend a script (gdscript) to the root node, we can define a derived class to change the type of the node accordingly.
But when use gdextension, I already define the derived class in cpp, then how can I change the root (node) type to that derived class?
