I have a problem with weekday labels, I cannot find a way to change them to this format
(from M to Mon etc…)

my code :

 <v-date-picker
     :weekday-format="customWeekDays"
     v-model="selectedDate"
     show-adjacent-months
 ></v-date-picker>

and

const customWeekDays = computed(() => {
  return ['Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa', 'Su'];
});

const selectedDate = ref<Date[] | undefined>(undefined);

const selectedDateDisplay = computed(() => {
  if (selectedDate.value instanceof Date) {
    return format(selectedDate.value, 'dd MMM yyyy');
  }
  return '';
});

I have tried this :weekday-format from (How to change day-format (M > Mo, F > Fr…) in Date/month pickers of Vuetify) prop but it doesnt seem to work for me
