1. How I can remove close button from QMessageBox?
2. How I can increase Title text?

class ErrorModal(QMessageBox):
    def __init__(self, parent: Optional[None] = None):
        super().__init__(parent=parent)
        self.findChild(QDialogButtonBox).setCenterButtons(True)
        font = self.font()
        font.setPointSize(20)
        self.setFont(font)
        self.setStyleSheet('QLabel{color:white;}')

        self.setStandardButtons(QMessageBox.Ok)
        self.setIcon(QMessageBox.Critical)
        self.setPalette(ErrorPalette())
