Editor Toolbar button?

Hello folks,
I am currently trying to program a Toolbar button but for the blueprint editor only. So my current way shown below adds the button to the level editor toolbar but I want the button to be in the blueprint editor toolbar. What do I need to change “LevelEditor.LevelEditorToolBar.PlayToolBar” to for this to work?

void FBAS_BPToCPPModule::RegisterMenus()
{
	// Owner will be used for cleanup in call to UToolMenus::UnregisterOwner
	FToolMenuOwnerScoped OwnerScoped(this);

	{
		UToolMenu* Menu = UToolMenus::Get()->ExtendMenu("LevelEditor.MainMenu.Window");
		{
			FToolMenuSection& Section = Menu->FindOrAddSection("WindowLayout");
			Section.AddMenuEntryWithCommandList(FBAS_BPToCPPCommands::Get().OpenPluginWindow, PluginCommands);
		}
	}

	{
		UToolMenu* ToolbarMenu = UToolMenus::Get()->ExtendMenu("LevelEditor.LevelEditorToolBar.PlayToolBar");
		{
			FToolMenuSection& Section = ToolbarMenu->FindOrAddSection("Settings");
			{
				FToolMenuEntry& Entry = Section.AddEntry(FToolMenuEntry::InitToolBarButton(FBAS_BPToCPPCommands::Get().OpenPluginWindow));
				Entry.SetCommandList(PluginCommands);
			}
		}
	}
}
