I'd say that you need to get access to the instance of the modal. I'm not that familiar with Vue.js, but you could try to add this to the main.js:

import * as bootstrap from 'bootstrap';
window.bootstrap = bootstrap;

And then, in App.vue, something like:

const close = () => {
  const modalInstance = bootstrap.Modal.getOrCreateInstance('#exampleModal');
  modalInstance.hide();
};
