How to get the active resource shader on the VisualShaderEditor? i tried with no luck :

var editor: EditorInterface = get_editor_interface()

	## 1) Inspector edited object
	var edited := editor.get_inspector().get_edited_object()
	#_visualEditor = editor.get_inspector()
	if edited is VisualShader:
		print("Found edited object")
		return edited
	
	if edited is ShaderMaterial:
		var shader = edited.shader
		if shader is VisualShader:
			print("found shader material shader")
			return shader

I got the opened shaders and the selected shader by a hack. By finding all ItemList nodes in the editor and filtering to the ones in the VisualShader editor.

func get_active_visual_shader():
	var opened_visual_shader_itemList = get_vse_item_list()
	for i in range(opened_visual_shader_itemList.item_count):
		var is_selected = opened_visual_shader_itemList.is_selected(i)
		if is_selected:
			var shader_name = opened_visual_shader_itemList.get_item_text(i)
			var shader = load("res://" + shader_name) as VisualShader
			return shader
	print("[ERROR]: No shader")
	return null
func get_vse_item_list() -> ItemList:
	var vse = EditorInterface.get_base_control()#.find_children("*", "VisualShaderEditor", true, false)
	# We search for ItemLists specifically inside this VSE instance
	var item_lists = vse.find_children("*", "ItemList", true, false)
	
	for list in item_lists:
		# Validation: The shader list is usually the one in the left panel.
		# In Godot 4, it is often a child of a VBoxContainer which is a child of an HSplitContainer.
		var parent = list.get_parent()
		var grand_parent = parent.get_parent() if parent else null
		
		if grand_parent is HSplitContainer:
			print("Bingo! Found the sidebar ItemList: ", list.get_path())
			return list
	return null
