Register_types import new resource

Question

So I am trying to import .vox files to the editor. For this I want to use CPP. I did not implement the _import yet because it seems it does not even get called. I tried using the vox plugin as an example and I left in the gdexample so I can check if even something gets loaded.
So to check if the vox_importer gets loaded I use “ERR_PRINT(“vox_importer hello”);” but this does not get called. And it should print the message /error message “imported vox” if i try to import a .vox file. I just want to create a working base but I think i am doing something wrong with the register_types.
Please someone help/explain. This is killing me ^^

register_types.cpp :

#include "register_types.h"

#include "gdexample.h"
#include "vox_importer.h"
#include <gdextension_interface.h>
#include <godot_cpp/core/defs.hpp>
#include <godot_cpp/godot.hpp>
#include <godot_cpp/variant/utility_functions.hpp>
using namespace godot;

void initialize_example_module(ModuleInitializationLevel p_level) {
	if (p_level == MODULE_INITIALIZATION_LEVEL_SCENE) {
		ClassDB::register_class<GDExample>();
	}
	if (p_level == MODULE_INITIALIZATION_LEVEL_EDITOR) {
		ClassDB::register_internal_class<vox_importer>();
	}	
	}

void uninitialize_example_module(ModuleInitializationLevel p_level) {
	if (p_level != MODULE_INITIALIZATION_LEVEL_SCENE) {
		return;
	}
}



extern "C" {
// Initialization.
GDExtensionBool GDE_EXPORT example_library_init(GDExtensionInterfaceGetProcAddress p_get_proc_address, const GDExtensionClassLibraryPtr p_library, GDExtensionInitialization *r_initialization) {
	godot::GDExtensionBinding::InitObject init_obj(p_get_proc_address, p_library, r_initialization);

	init_obj.register_initializer(initialize_example_module);
	init_obj.register_terminator(uninitialize_example_module);
    
	init_obj.set_minimum_library_initialization_level(MODULE_INITIALIZATION_LEVEL_SCENE);

	
	return init_obj.init();
}
}

vox_importer.cpp:

#include "vox_importer.h"
#include <godot_cpp/variant/utility_functions.hpp>

    return true;
}

So i think I am doing something fundamentally wrong.

• For example in this Tutorial for GDScript and C# they also need to use this command:
  EditorPlugin.add_import_plugin

• do i need to do something with TOOLS_ENABLED ? And how do i enable them in the editor?

• Is my working process wrong? I followed the gdexample tutorial and am using the godot cpp and then scons and then just open the demo projekt with godot and try to drag and drop a .vox file into it and expect a message inside the terminal

• should this also be set to editor? init_obj.set_minimum_library_initialization_level(MODULE_INITIALIZATION_LEVEL_SCENE);

Can someone pls help
