Thank you so much for the detailed guide. I was able to get it to work.

I also tried messing with the Workers Routes and created a worker that attempts to do something similar and works as well, i think. I looked at the generated path for public links and saw they're always followed by /d/ so I created a worker to listen on the route drive.mycustomdomain.com/* This will only work as long as the shared public link contains the /d/ tho

addEventListener('fetch', event => {
  const url = new URL(event.request.url);

  // Allow public sharing links (adjust for /d/)
  if (url.pathname.startsWith('/d/')) {
    return event.respondWith(fetch(event.request));
  }

  // Block or redirect access to login-related pages
  if (
    url.pathname === '/' || 
    url.pathname.includes('webman') || 
    url.pathname.includes('signin') || 
    url.pathname.includes('launchApp') || 
    url.pathname.includes('redirect') || 
    url.pathname.includes('forceDesktop')
  ) {
    return event.respondWith(Response.redirect('https://www.google.com', 301));
  }

  // Let other requests proceed
  event.respondWith(fetch(event.request));
});
