Should clerkMiddleware be fed async function and use auth.protect() instead of auth().protect()?

I am having issues reproducing the route protection step.

With https://github.com/WebDevSimplified/parity-deals-clone/blob/3661f28d75205d3db84d4b86c82ae535acd11272/src/middleware.ts#L12

I am getting TypeError: auth(...).protect is not a function.

And with auth.protect() instead I get

Looked up the Clerk doc at https://clerk.com/docs/references/nextjs/clerk-middleware and it seems they recommend:

auth.protect()
AND feed clerkMiddleware an asyn function

From https://clerk.com/docs/references/nextjs/clerk-middleware:

import { clerkMiddleware, createRouteMatcher } from '@clerk/nextjs/server'

const isProtectedRoute = createRouteMatcher(['/dashboard(.*)', '/forum(.*)'])

export default clerkMiddleware(async (auth, req) => {
  if (isProtectedRoute(req)) await auth.protect()
})

export const config = {
  matcher: [
    // Skip Next.js internals and all static files, unless found in search params
    '/((?!_next|[^?]*\\.(?:html?|css|js(?!on)|jpe?g|webp|png|gif|svg|ttf|woff2?|ico|csv|docx?|xlsx?|zip|webmanifest)).*)',
    // Always run for API routes
    '/(api|trpc)(.*)',
  ],
}

or maybe the current code is fine ifauth is also imported from @clerk/nextjs/server ?
