Proxy authentication REQUIRES the browser to be configured to use a proxy,
if not the browser MUST (per the HTTP standard) refuse to participate in
any such authentication requests.

And if you look on this from a security perspective it is obvious this
must be the case as the browser has no way of knowing or even less
identifying the proxy when you transparently hijack the browsers requests
and sends them to the proxy instead of the origin web server as requested
by the browser.
