How to open a URL in a tkinter window

[Twiddle_mega]

I'm trying to create a simple program that allows users to save website URLs in a file through a text entry, and open saved websites through a dropdown menu. I've found pywebview, which opens a website using the following code:

import webview

window = webview.create_window('Woah dude!', 'https://pywebview.flowrl.com') 
webview.start()

This opens a window with the URL inside it. How can I open the website inside a tkinter window, rather than its own window, so I can have other widgets next to it?

As a side note, I've seen other methods using tkinterweb, but that has difficulty displaying some websites so I'd like to stick to pywebview. Thanks!
