How to include folium map into PyQt5 application window?

Question

I would like to ask how do I go about including a folium map into PyQt 5 window application such that the map does not take up the whole window. I have found a similar post

The problem has nothing to do with a QWebEngineView or folium but how to place widgets inside the window, if so, then a solution is to use layouts in this case I will use the following structure: First a central widget is established, inside this one QHBoxLayout , and in the QHBoxLayout a QWidget is added as a container to the left side where a QVBoxLayout will be placed where the buttons will be, and to the right side the QWebEngineView:

import io
import sys

import folium

from PyQt5 import QtCore, QtGui, QtWidgets, QtWebEngineWidgets


class Window(QtWidgets.QMainWindow):
    def __init__(self):
        super().__init__()
        self.initWindow()

    def initWindow(self):
        self.setWindowTitle(self.tr("MAP PROJECT"))
        self.setFixedSize(1500, 800)
        self.buttonUI()

    def buttonUI(self):
        shortPathButton = QtWidgets.QPushButton(self.tr("Find shortest path"))
        button2 = QtWidgets.QPushButton(self.tr("Another path"))
        button3 = QtWidgets.QPushButton(self.tr("Another path"))

        shortPathButton.setFixedSize(120, 50)
        button2.setFixedSize(120, 50)
        button3.setFixedSize(120, 50)

        self.view = QtWebEngineWidgets.QWebEngineView()
        self.view.setContentsMargins(50, 50, 50, 50)

        central_widget = QtWidgets.QWidget()
        self.setCentralWidget(central_widget)
        lay = QtWidgets.QHBoxLayout(central_widget)

        button_container = QtWidgets.QWidget()
        vlay = QtWidgets.QVBoxLayout(button_container)
        vlay.setSpacing(20)
        vlay.addStretch()
        vlay.addWidget(shortPathButton)
        vlay.addWidget(button2)
        vlay.addWidget(button3)
        vlay.addStretch()
        lay.addWidget(button_container)
        lay.addWidget(self.view, stretch=1)

        m = folium.Map(
            location=[45.5236, -122.6750], tiles="Stamen Toner", zoom_start=13
        )

        data = io.BytesIO()
        m.save(data, close_file=False)
        self.view.setHtml(data.getvalue().decode())


if __name__ == "__main__":
    App = QtWidgets.QApplication(sys.argv)
    window = Window()
    window.show()
    sys.exit(App.exec())
