I have taken alexa-viewer as a reference application and implemented a popup window using CMake. Popup window was appearing on top of the AGL home screen application without any issues, added one button on the popup window named as FullView. Implemented onReleased callback for the FullView button and called aglShell activate_app function call,
aglShell->activate_app(nullptr, application_id, nullptr);
But activation did not happen when I released the FullView button, from logs noticed some segmentation core dump issues. Please find the following debugging logs for more information,

Please help me and provide the correct way of activating Qt/Qml applications using agl-shell-protocols.
