How to add QLineEdit to QMessageBox PyQt5

I want a copyable text on my QMessageBox so I thought I can put a QLineEdit on QMessageBox then set the text of QLineEdit whatever I want, so user can choose the text and copy it.

But I couldn't success. Is there a way to add QLineEdit to QMessageBox or make a copyable text on QMessageBox?

by playing with QMessageBox.informativeText(), QMessageBox.detailedText() and QMessageBox.textInteractionFlags() i found the following:

QMessageBox.informativeText() and QMessageBox.detailedText() are always selectable, even if QmessageBox.textInteractionFlags() are set to QtCore.Qt.NoTextInteraction. QMessageBox.detailedText() is shown in a textedit. QMessageBox.setTextInteractionFlags() only acts on QmessageBox.text(). The use of these kinds of text is descripted in documentation of QMessageBox. By flags you can set the text editable and/or selectable, see enum TextInteractionFlags.

Here an working example with selectable text in QmessageBox.detailedText():

import sys 
from PyQt5 import QtWidgets, QtCore

class MyWidget(QtWidgets.QWidget): 
    def __init__(self): 
        QtWidgets.QWidget.__init__(self) 
        self.setGeometry(400,50,200,200)

        self.pushButton = QtWidgets.QPushButton('show messagebox', self)
        self.pushButton.setGeometry(25, 90, 150, 25)
        self.pushButton.clicked.connect(self.onClick)

    def onClick(self):
        msgbox = QtWidgets.QMessageBox()
        msgbox.setText('to select click "show details"')
        msgbox.setTextInteractionFlags(QtCore.Qt.NoTextInteraction) # (QtCore.Qt.TextSelectableByMouse)
        msgbox.setDetailedText('line 1\nline 2\nline 3')
        msgbox.exec()

app = QtWidgets.QApplication(sys.argv)
w = MyWidget()
w.show()
sys.exit(app.exec_())
