defineNuxtRouteMiddleware not working

File is in middleware/nuxtRouteMiddleware.ts as docs imply.

export default defineNuxtRouteMiddleware(async (to) => {
  console.log("Middleware running"); // Nothing is logged
});

export default defineNuxtRouteMiddleware(async (to) => {
  console.log("Middleware running"); // Nothing is logged
});

export default defineNuxtRouteMiddleware(async (to) => {
  console.log("Middleware running"); // Nothing is logged
});

export default defineNuxtRouteMiddleware(async (to) => {
  console.log("Middleware running"); // Nothing is logged
});

This seems like a super simple use case, yet I can't even get it to console log?
