I tried to sign and notarize example application "simplebrowser" from Qt5.12.7 examples.
If I sign the main application: simplebrowser.app/Contents/MacOS/simplebrowser with deep and runtime options It works perfect, but I cannot notarize this bundle because I have to sign simplebrowser.app/Contents/Frameworks/QtWebEngineCore.framework/Helpers/QtWebEngineProcess.app/Contents/MacOS/QtWebEngineProcess too. If I make this, I can notarize the application. But the program does not work on websites with Java Script.
Also I tried this solution: https://forum.qt.io/topic/102212/qtwebengine-signing-issues It does not work
