Easepick – close calender on second click on input field

I would like to close the calander, if the user clicks again on the input field.
Do you know a good way to realise that?

const picker = new easepick.create({
    element: document.getElementById('datepicker'),
    css: [
    'https://cdn.jsdelivr.net/npm/@easepick/bundle@1.2.1/dist/index.css',
    ],
    calendars: 2,
    grid: 2,
    plugins: ['LockPlugin','RangePlugin'],
    LockPlugin: {
    minDate: new Date(),
    },
    RangePlugin: {
    tooltip: true,
    startDate: new Date(),
    endDate: new Date('2027-12-31'),
    locale: {
        one: 'day',
        other: 'days',},
    },    
});

Thank you in advance for your help!
