how to set the position of qdialog in pyside6

Question

Unable to position the dialog @ the bottom right of window in order to set the position setGeometry(...) method is used but its always @ center. How to position the dialog to the bottom right?

Execution starts from keyWindow.py(main) and when numeric keys are pressed it opens dialog which is located in keyDialog.py

keyWindow.py

import sys

from PySide6.QtWidgets import QWidget, QMainWindow, QApplication, QHBoxLayout, QVBoxLayout, QDialog
from PySide6.QtGui import QKeyEvent
from PySide6.QtCore import Qt

import KeyDialog


class MainWindow(QMainWindow):
    numericDic = {
        Qt.Key_0: 0,
        Qt.Key_1: 1,
        Qt.Key_2: 2,
        Qt.Key_3: 3,
        Qt.Key_4: 4,
        Qt.Key_5: 5,
        Qt.Key_6: 6,
        Qt.Key_7: 7,
        Qt.Key_8: 8,
        Qt.Key_9: 9
    }

    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        self.resize(600, 500)

    def keyPressEvent(self, keyEvent: QKeyEvent):
        if keyEvent.isAutoRepeat():
            return
        key = keyEvent.key()
        print(f"keyPressEvent {key}")
        if key in MainWindow.numericDic.keys() or key == Qt.Key_Plus or key == Qt.Key_Minus:
            keyDialog = KeyDialog(self)
            keyDialog.exec()

    # def keyReleaseEvent(self, keyEvent: QKeyEvent):
    #     if keyEvent.isAutoRepeat():
    #         return
    #     key = keyEvent.key()
    #     print(f"keyReleaseEvent {key}")


if __name__ == "__main__":
    app = QApplication(sys.argv)
    win = MainWindow()
    win.show()
    sys.exit(app.exec())

keyDialog.py

        ownWidth = 200
        ownHeight = 40
        bottomGap = 30
        rightGap = 40
        self.setGeometry(width - ownWidth - rightGap, height - ownHeight - bottomGap, ownWidth, ownHeight)
        self.layout = QGridLayout()
        self.box = QDoubleSpinBox()
        self.box.editingFinished.connect(self.boxValueChanged)
        self.box.setMinimum(float("-inf"))
        self.box.setMaximum(float("+inf"))
        self.box.setValue(3.5)
        self.box.setSingleStep(0.5)
