embedding a web view within Tkinter-based application

[mkeyno]

I am developing a Python application using PySimpleGUI (which leverages Tkinter). To implement user authentication, I need to open a login page URL within my application. While the webbrowser library allows me to open URLs, it encounters issues with HTTPS pages, specifically Gmail authentication.
I am investigating pywebview as a potential solution for embedding a web view within my Tkinter-based application. My goal is to capture the server callback from the authentication page within my main window.

Any assistance in achieving this integration would be greatly appreciated
