world panel overhead ?

this seems to work

bl_label = “Layout Demo”
bl_space_type = ‘PROPERTIES’
bl_region_type = ‘WINDOW’
bl_context = “world”

I can add a new panel in the scene property pane
but not in the world one

bl_label = “Layout Demo”
bl_idname = “SCENE_PT_layout”
bl_space_type = ‘PROPERTIES’
bl_region_type = ‘WINDOW’

bl_context = “scene”

bl_context = “World”

can someone point out how to correct this

not certain if this bl_idname is it needed

there might also the new tab which might come into play may be

thanks

bl_context needs to be lowercase

class HelloWorldPanel(bpy.types.Panel):
    """Creates a Panel in the Object properties window"""
    bl_label = "Hello World Panel"
    bl_idname = "OBJECT_PT_hello"
    bl_space_type = 'PROPERTIES'
    bl_region_type = 'WINDOW'
    bl_context = "world"
