Adding QMessageBox System Icon into QDialog

Question

First of all, I want to use QMessageBox subclass to embed a scroll area layout in between QMessageBox informative text and its button at the bottom. But the scroll area overlaps the icon like this

class CustomizedMessagebox(QMessageBox):
    def __init__(self,parent,dic):
        QMessageBox.__init__(self,parent)
        self.setIcon(QMessageBox.Warning)
        self.setText("Sample Warning Text Here")
        scroll = QScrollArea(self)
        scroll.setWidgetResizable(True)
        self.content = QWidget()
        scroll.setWidget(self.content)
        lay = QVBoxLayout(self.content)
        for item in [[1,2],[3,4],[5,6],[7,8],[9,0]]: #just for scroll able example list
            lay.addWidget(QLabel("{} - {}".format(item[0],item[1]), self))
        self.layout().addWidget(scroll, 1, 0, 1, self.layout().columnCount())
        #self.setStyleSheet("QScrollArea{min-width:200 px; min-height: 200px}") #style that i want to add later on
        self.addButton('Understood',self.AcceptRole)

So I decided to create QDialog instead, but I wonder how can I add QMessageBox.Warning icon (also including QMessagebox title and informative text styling) into QDialog, is it possible?. If not then how could I create distance between QMessagebox Icon and its text from the scroll area layout? (because it seems way simpler solution IMO), ps: I really want to minimize external media for icon since my app only does a simple task so that's why I'm really curious if I could take QMessagebox icon instead or if there's no other way I'll be following whatever it is.

The solution is to remove the QDialogButtonBox, add the QScrollArea and then add the removed QDialogButtonBox:

from PySide2.QtWidgets import (
    QApplication,
    QDialogButtonBox,
    QLabel,
    QMessageBox,
    QScrollArea,
    QVBoxLayout,
    QWidget,
)


class CustomizedMessagebox(QMessageBox):
    def __init__(self, parent=None):
        QMessageBox.__init__(self, parent)
        self.setIcon(QMessageBox.Warning)
        self.setText("Sample Warning Text Here")
        self.addButton("Understood", QMessageBox.AcceptRole)

        scroll = QScrollArea(widgetResizable=True)
        self.content = QWidget()
        scroll.setWidget(self.content)

        box = self.findChild(QDialogButtonBox)
        self.layout().removeWidget(box)

        self.layout().addWidget(
            scroll, self.layout().rowCount(), 0, 1, self.layout().columnCount()
        )
        self.layout().addWidget(
            box, self.layout().rowCount(), 0, 1, self.layout().columnCount()
        )

        lay = QVBoxLayout(self.content)
        for item in [[1, 2], [3, 4], [5, 6], [7, 8], [9, 0]]:
            lay.addWidget(QLabel("{} - {}".format(item[0], item[1]), self))


app = QApplication([])
w = CustomizedMessagebox()
w.exec_()
