How to disable deselection of items in ListView?

Hi,
i'm new to PrimeVue 3. I just build up a little admin interface for my ReCoS project and came across this question, where i didn't found a solution. Maybe someone can help me.
How to disable deselection of items in ListView?
I have a Listview

Code: Select all

        <Listbox
          v-model="activeAction"
          :options="profile.actions"
          optionLabel="name"
          listStyle="max-height:500px"
          class="no-border"
          v-on:change="checkChange($event)"
        >
        </Listbox>

and i want to deactivate the deselction of the items. Every time one item should be selected. Programatically i select the first item on changing the underlying list. There is only one exception, if there is no item in the list. How can I achieve this?

As far as I know there isn't a way. I hacked it by listening to the @change event, storing the last selection, and if it gets changed to null then resetting it back to the last selection.
