PyQt5 QWebEngineView [How to enable spell-checking and correct spelling suggestions]

Question

I need help with a PyQt5 tool I created to view and work with a Zendesk form that has a rich text edit widget. My code is quite big, so the code below pretty much does the same as mine.

I need help making the tool recognize the incorrectly spelt words and show suggestions for the correct spelling when right-clicked, as on Chrome or any other browser.

I tried importing the Grammarly web extension but failed. I downloaded the PC version of it, and it's not even working properly with the tool. It's working fine with everything else, though.

Thanks in advance.

Code:

from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEngineProfile

class BrowserTool(QMainWindow):
    def __init__(self):
        super().__init__()

        self.resize(800, 600)

        # Create the web view
        self.web_view = QWebEngineView(self)

        # Create a web engine profile
        profile = QWebEngineProfile.defaultProfile()
        profile.setSpellCheckEnabled(True) # Enable spell check

        # Load the URL
        self.web_view.setUrl(QUrl('https://onlinehtmleditor.dev/'))

        # Set the web view as the central widget
        self.setCentralWidget(self.web_view)

if __name__ == '__main__':
    app = QApplication([])
    browser_tool = BrowserTool()
    browser_tool.show()
    app.exec_()

I tried using PySpellChecker, Textblob and other libraries but still didn't detect the incorrectly spelt word or showed suggestions when right-clicked.
