How to remove right-arrow from QPushButton + QMenu?

Question

PyQt

Here is a sample code

menu = QMenu()
menu.addAction('Settings', lambda: print('hello!'))
        
self.btn_dialog = QPushButton('Я кнопка')
self.btn_dialog.setMenu(menu)
self.layout_wrapper.addWidget(self.btn_dialog)

Just initializing the menu and then pushing it under the button. Everything would be fine, but QMenu adds an arrow to QPushButton:
