Embedding a QQuickWidget in a Layout (or in a QWidget) in Python

I use Python and Pyside2, I try to insert a QQuickWidget inside a Qwidget or inside a Layout but I haven't find a solution. I try with this code:

view = QQuickWidget()
view.setSource(QUrl.fromLocalFile("main.qml"))

but QQuickWidget start in another windows. I try use:

Layout.addWidget(view)

but it required a QWidget and don't work with QQuickWidget. I found this similar question (in C) but it don't work in Python: Adding QQuickWidget in QStackedWidget

I have try QQmlApplicationEngine and QQuickView, but problem is the some.

Can you help me ?

Edit: main.qml file is:

import QtQuick 2.0
import QtQuick.Window 2.0
import QtLocation 5.6
import QtPositioning 5.6

Window {
    width: 300
    height: 300
    visible: true

    Plugin {
        id: mapPlugin
        name: "esri"
    }

    Map {
        anchors.fill: parent
        plugin: mapPlugin
        center: QtPositioning.coordinate(39.2160, 9.1344)
        zoomLevel: 16
    }
}

The problem is that the root element is a Window that will create a window, the solution is to use an Item:

import QtQuick 2.0
import QtLocation 5.6
import QtPositioning 5.6

Item {
    width: 300
    height: 300

    Plugin {
        id: mapPlugin
        name: "esri"
    }

    Map {
        anchors.fill: parent
        plugin: mapPlugin
        center: QtPositioning.coordinate(39.2160, 9.1344)
        zoomLevel: 16
    }
}
