how to customize ngxbootstrap daterangepicker?

Question

I'm using ngx bootstrap datepicker i have a requirement to show multiple date range is calender.when open calender view should be months which show selected multiple months.on click that selected month it show selected dates in that month.

when click on one particular month selected days in that month have to show

so after refering https://valor-software.com/ngx-bootstrap/#/components/datepicker?tab=overview I created bsdaterange picker with minmode'month' but not able to show dates when click on a particular month.

                                <input  class="input-box form-control datePicker" #dp="bsDaterangepicker" bsDaterangepicker
                                    [readonly]="true" [bsValue]="value.bsRangeValue"     [datesEnabled]="value.datesEnabled"
                                    [bsConfig]="{rangeInputFormat : 'DD.MM.YYYY',minMode: 'month',displayMonths:1}" name="mydate"
                                     (onShown)="onOpenCalendar($event,value)" (bsValueChange)="dateRangeChange($event)" 
                                    >

Is there any solution in ngxbootstrap to fullfill this requirement
