title: Qt Windows 10 notifications
body: <p>I am trying to make use of the Windows 10 notifications system (the ones poping out from the right side panel, available from notifications tray icon) in my Qt 5.13.0 program. I am looking at the Windows extras class: <a href="https://doc.qt.io/qt-5/qtwinextras-index.html" rel="nofollow noreferrer">https://doc.qt.io/qt-5/qtwinextras-index.html</a> but cannot find any API for such thing. Is it even possible somehow in Qt?</p>
