        // As amazing as it may sound, there's a three year old bug that LinkedIn
        // knows of but doesn't fix, which is simply the group posts URL is not
        // returned when we create the post, and when the post endpoint is queried
        // it returns a URL containing an incorrect domain: api.linkedin.com
        // instead of www.linkedin.com. They acknowledge this in the "Known Issues"
        // section of the groups API documentation and say the workaround is simple:
        // just swap the domains. Well, thanks for nothing. Would it be so hard for
        // them to return a public URL along with the response of the creation?...
        // So we need to make another API call to fetch the correct URL, because
        // it's not even possible to generate it manually.
