I try to programmatically launch the MDBModal but it doesn't show up. Any idea ?

Template :

<a class="me-3 text-dark" @click="launchModal()" href="#">Launch Modal</a>
<MDBModal id="modalExemple" tabindex="-1" labelledby="modalExemple" v-model="modalExemple">
<MDBModalHeader>
  <MDBModalTitle id="modalExempleLabel" class="text-dark">Exemple</MDBModalTitle>
</MDBModalHeader>
<MDBModalBody class="my-4">
  <div class="text-start text-dark">
    Exemple
  </div>
</MDBModalBody>

Script :

let modalExemple = ref(false);
function launchModal() {
    modalExemple = true;
}
