  apollo: {
    entry: gql`MY QUERY`
  },
  components: { TemplatePresentationPage },

  props: {},
  setup() {

Ok i found a solution:

1. Need ton install vue composable (https://v4.apollo.vuejs.org/guide-composable/setup.html)
2. See this page (https://v4.apollo.vuejs.org/guide-composable/query.html#usequery)
