Access members of `QVariant(PySide::PyObjectWrapper)` on QML

Developer123

In my backend (python, PySide2), I have a signal of type:

sendData = Signal(object)

which sends a python dictionary such as:

data = {'1': 123,
        '2': 456,
        '3': 789}

Using the function call:

self.sendData.emit(data)

On the "frontend", I have QML on QtQuick, which when I print the received data, I get:

qml: QVariant(PySide::PyObjectWrapper, )

How can I access e.g. data['1'], to get 123 ?
