        Because of Google's cors rules, we can't just do a request to google ics
        from the frontend. Google is blocking CORS request in it's responses headers.
        The only way to do it from the frontend is to use Google Calendar API with an API key
        This is not especially desirable as your API key is going to be provided to the frontend.

        This is why we have this backend based solution.
