how can I set 2 range dates with js code in air-datepicker?

Remaking code from air-datepicker (with range = true ) 2.2.3 into v3.3.5 I did not find how can I set 2 range dates with js code.

Clicking on button I need to add sevaral days to first date, like I did under 2.2.3:

   const dateRangeInput = $('.date-range');
   dateRangeInput.data('datepicker').selectDate([date1, date2]);

But reading docs at https://air-datepicker.com/docs I did not find how can I dop this under v3.3.5 ?

After reading the docs it looks like that I need to cretate a new instance of AirDatepicker, when I need to set selectedDates programmatically on some event(not only when AirDatepicker is inited), like :

var dp = new AirDatepicker('.date-range', {
                multipleDates: true,
                range: true,
                multipleDatesSeparator: ' - ',
                selectedDates: [date1, date2]
            })

I did not find any other way, the same as when I need to run onSelect method by clicking on the button of the form... I dislike this way, how can I do it in better way?
