Have multiple layouts for one page depending on condition

const userStore = useUserStore();

const {
  userIsLoggedIn,
  userHasAcceptedTerms,
  storeIsLoading,
} = storeToRefs(userStore);

const layout = computed(() => {
  return userIsLoggedIn?.value ? 'default' : 'no-auth';
});

definePageMeta({
  layout // OR   : userIsLoggedIn?.value ? 'default' : 'no-auth'  // "userIsLoggedIn is not defined"
})
