How do I add a new property in definePageMeta and access it in the application, whether in middleware or via useRoute()

On any page, for example:

definePageMeta({
  myProperty : "value string or array or any"
});

For example, middleware :

export default defineNuxtRouteMiddleware(async (to) => {
  if(to.meta.myProperty === "any") {
    //code
  }
});

or in any Page :

const route = useRoute();

if(route.meta.myProperty) {
  // code
}

I want it to be available when writing, for example, to.meta.| show in list and click enter to add.
