Adding DatePicker functions to datePickerProps

[mod49]

Hello everyone,
vuetify's DatePicker supports several functions like header-date-format, title-date-format, weekday-format or year-format. How can i define them in the datePickerProps of vuetify-datetime-picker?
What i tried looks like this:

datePickerProps: {
  locale: 'de_de',
  color: 'accent',
  eventColor: 'accent',
  headerColor: 'primary',
  headerDateFormat: (isoDate) => {
    const date = this.formatDate(isoDate)
    return date
  }

But that did not work. Has anyone successfully added those functions to their props?

Regards
Volker

Hello everyone,
sorry for the late replay. I have solved my problem in the meantime:
datePickerProps: {
headerDateFormat: (e) => {
console.log('### headerDateFormat: ', e)
return moment(e).format('MMM YYYY')
}
}

Best regards
Volker
