How can one utilize the this.$q Quasar object within the setup() function in Vue 3 Composition API?

Here is a component script written in Options Api:

<script>
export default {
  data() {
    return {
      model: null,
    };
  },
  computed: {
    isMobile() {
      return this.$q.screen.xs || this.$q.screen.sm;
    }
  }
};
</script>

If you want to rewrite it using the Composition Api in Typescript, here's an example. Note that accessing the `this.$q` variable might need to be handled differently.

<script lang="ts">
import { computed, defineComponent, ref, ComputedRef } from 'vue';

export default defineComponent({
  name: 'QuasarTest',
  setup() {
    const isMobile: ComputedRef<boolean> = computed((): boolean => {
      // Accessing `this.$q` may require a different approach
      return true; // Placeholder for accessing $q screen properties
    });
    return {
      isMobile,
      model: ref(null),
    };
  }
});
</script>

In case it is required later on. The most appropriate solution would be to utilize the composable: useQuasar as specified in the documentation
