[bug] Error loading docs.google.com in a webview

Describe the bug

I'm trying to use the Google Docs creation page within a Tauri webview. While the Google login challenge completes successfully, the Google Docs page fails to load afterward, showing this error message:

We believe the issue might be due to Google Docs attempting to download and install an extension to enable collaborative editing which may not be permitted by default in Tauri's webview environment.

Is there a configuration or workaround we can add to tauri::WebviewBuilder to address this loading issue?

Reproduction

This repository contains a basic Tauri app that opens a single webview pointing to https://docs.google.com/document/u/0/create. Upon launching the app, you’ll be prompted to log in with your Google account. After logging in, the webview attempts to load the Google Docs editor but fails to fully display the page.
