Receive gestures in PyQt5 (for Android)

Ok, this question has been asked before - but I didn't find an answer yet..

I'm trying to left/right swipe between images using a QLabel but I didn't manage to receive any gesture events yet with my PyQt5 based application. Here is what I have:

class MyViewer(QtWidgets.QLabel):
    def __init__(self, parent=None):
        super().__init__(parent=parent)
        self.setAttribute(QtCore.Qt.WA_AcceptTouchEvents)  # just gave it a try
        self.grabGesture(QtCore.Qt.SwipeGesture)

    def event(self, event):
        if event.type() == QtCore.QEvent.Gesture:  # <= this won't happen
            print("Hello event!")
        return super().event(event)

I also tried to look for QtWidgets.QGestureEvent but even when I just print out event.type() I only see events seemingly unrelated to any gestures (except some QToucheEvent instances)

Similar questions are this one, this one, this one and I even read some documentation but I didn't see a working example yet. Only questions and example C++ snippets..

I'm using PyQt5.15.0 for both Linux and Android and I didn't see a single trace of anything gesture-ish yet. What did I forget to do? Does the parent have to be set up somehow?
