Is it possible to access React Router instance outside of React application?

I'm writing a browser extension for a web application that uses React Router. I want to change pages of that React application.
Is it possible to access React Router instance outside of React application

The main trick is that I don't control the source code

If the application is using React Router Data mode, the result of createBrowserRouter is a router object that has method like router.navigate(path).

But if you don't control the source code of the application, and the application is not exposing this router instance globally like in window.router there's no way to access it.

The only option I can think in that case is to manipulate the URL directly and trigger a navigation by doing this, but without being a client-side navigation, basically causing a new document request.

Exactly, I'm doing the navigation by tweaking the URL directly
So the basic thought was, if someone knows a hack to get into a minified React Application and somehow find a React Router instance there. I honestly have no idea wether someone tried that or not, but it seems quite possible since all the code is literally available for the web app

You would need to replace the built code at runtime to make the router instance available on window.router, which I doubt browsers will allow.

You are probably right, but that's a worthy idea, I'll try it out
