Currently it is not possible for JAWS to process plain text element in QML, e.g Text. Additionally, JAWS detection also not working with its shortcut navigation, e.g moving through heading using "H" key on WebEngineView.

Snippet for observing the behavior of WebEngineView with JAWS:

Window {
    width: 1024
    height: 750
    visible: true
    WebEngineView {
        anchors.fill: parent
        url: "https://www.qt.io"
    }
}
