Вывод текста на форму с потока с помощью сигналов

Question

Нужна помощь в следующей задаче:

Есть главное окно MainWindow и есть отдельный класс потока в котором есть текст. Подскажите как с помощью сигналов на форму plainTextEdit которая находится на главной форме вывести текст через сигналы?

Код главного окна :

import sys

from PySide6.QtWidgets import *

from Controller.Potok_Controller import Potok_Controller
from View.ui_potok import Ui_MainWindow

class MainWindow(QMainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)

        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)

        self.ui.pushButton.clicked.connect(self.open_window)

    def open_window(self):
        self.myThread = Potok_Controller()
        # self.myThread.mysignal.connect(self.sendText)
        self.myThread.start()

if __name__ == '__main__':
    app = QApplication()
    window = MainWindow()
    window.show()
    sys.exit(app.exec())

UI код главного окна:

        self.verticalLayout_2.addWidget(self.plainTextEdit)


        self.verticalLayout.addWidget(self.frame)

        self.frame_2 = QFrame(self.centralwidget)
        self.frame_2.setObjectName(u"frame_2")

        self.pushButton.setObjectName(u"pushButton")

        self.verticalLayout_3.addWidget(self.pushButton)


        self.verticalLayout.addWidget(self.frame_2)

        MainWindow.setCentralWidget(self.centralwidget)

        self.retranslateUi(MainWindow)

        QMetaObject.connectSlotsByName(MainWindow)
    # setupUi

    def retranslateUi(self, MainWindow):
        MainWindow.setWindowTitle(QCoreApplication.translate("MainWindow", u"MainWindow", None))
        self.pushButton.setText(QCoreApplication.translate("MainWindow", u"\u0421\u0442\u0430\u0440\u0442 \u043f\u043e\u0442\u043e\u043a\u0430", None))
    # retranslateUi

Код потокового класса:

import time

from PySide6.QtCore import QThread

class Potok_Controller(QThread):
    def __init__(self, parent=None):
        super(Potok_Controller, self).__init__(parent)

    def txt(self):
        txt1 = 'test1'
        time.sleep(1)
        txt2 = 'test2'
        time.sleep(1)
        txt3 = 'test3'

    def run(self):
        self.txt()

сигналы-слоты для PySide6

from PySide6.QtCore import Signal

class Potok_Controller(QThread):

    mysignal = Signal(str)

    def __init__(self, parent=None):
        super(Potok_Controller, self).__init__(parent)

    def txt(self):
        self.mysignal.emit('test1')
        time.sleep(1)
        self.mysignal.emit('test2')
        time.sleep(1)
        self.mysignal.emit('test3')

    def run(self):
        self.txt()

Теперь в окне

def open_window(self):
    self.myThread = Potok_Controller()
    self.myThread.mysignal.connect(lambda text: self.plainTextEdit.setPlainText(text))
    self.myThread.start()
