Accessing dialog buttons through ref

[jfrag]

Hi,

I want to access dialog actions buttons from dialog object but $dialog buttons_ propertie is empty

<ui-dialog ref="dialogCreate" class="mdc-dialog--not-scrollable" v-model="dialogCreateOpen">
  <ui-dialog-title><?= _('New user') ?></ui-dialog-title>
  <ui-dialog-content class="pt2">
    <ui-form type="|">
      <ui-form-field>
        <ui-autocomplete v-model="addUser.name" :source="addUserSource" fullwidth remote required outlined delay="500" @search="searchUserCreate" @selected="onSelectUser"><?= _('Name') ?></ui-autocomplete>
      </ui-form-field>
      <ui-form-field>
        <ui-select outlined fixed fullwidth v-model="addUser.role" :options="roles"><?= _('Role') ?></ui-select>
      </ui-form-field>
    </ui-form>
  </ui-dialog-content>
  <ui-dialog-actions>
    <ui-button @click="closeDialogCreate"><?= _('Cancel') ?></ui-button>
    <ui-button @click="saveDialogCreate"><?= _('Save') ?></ui-button>
  </ui-dialog-actions>
</ui-dialog>

export default {
  methods: {
    closeDialogCreate() {
      console.log(this.$ref.dialogCreate.buttons_) //undefined
    }
  }
}

I didn't find a solution for accessing dialog buttons on $dialog object too

Any solution ?

Thank's
