u need copy Web Browser Plugins&Rewrite,if u need h.264,265 Surport U shorld upgrade CEF core ，now rewrite UWebBrowser::RebuildWidget()in SNew(SWebbrowser) add this Code;

.OnCreateWindow(FOnCreateGoodWindowDelegate::CreateLambda([](const TWeakPtr<IGoodWebBrowserWindow>& NewBrowserWindow, const TWeakPtr<IGoodWebBrowserPopupFeatures>& PopupFeatures)
		{
			// Initialize a dialog
			auto DialogMainWindow = SNew(SWindow)
				.Title(FText::FromString(TEXT("Chrome Debugging Tools")))
				.ClientSize(FVector2D(700, 700))
				.SupportsMaximize(true)
				.SupportsMinimize(true)
				[
					SNew(SVerticalBox) +
					SVerticalBox::Slot()
						.HAlign(HAlign_Fill)
						.VAlign(VAlign_Fill)
						[
							SNew(SGoodWebBrowser, NewBrowserWindow.Pin())
						]
				];
			FSlateApplication::Get().AddWindow(DialogMainWindow);
			return true;
		}));
	}
	IGoodWebBrowserSingleton* WebBrowserSingleton = IGoodWebBrowserModule::Get().GetSingleton();
	WebBrowserSingleton->SetDevToolsShortcutEnabled(true);

if u don’t want to mistake,close Bridge plugin,becuse Bridge Plugin ref Engine build in Cef source FBridgeUIManagerImpl::CreateBridgeTab,cef core Version diff then compling Engine Will Crash.
now u can open dev tools,And use it after packaging
