Laravel Route to other port/application

I have a laravel 8 project running on port 8000 and metabase (an analytic framework) running on port 3000.

metabase itself is password protected. But if possible I would like to make normal users unable to even get to the login screen of metabase. My idea was that metabase exposes port 3000 only to localhost and laravel forwards port 3000 inside a middlewarte protected route.

I was hoping for a solution which would look something like this:

Route::middleware(['auth','isAdmin'])->prefix('metabase')->group(function() {
    // forward port 3000 here
});
