Event after the DatePicker component is selected

[He-Wu]

Is your feature request related to a problem? Please describe.
I am using the DatePicker component to complete the date range selection function. I use the DatesChanged event to trigger the event every time I select a time. The parameter of the event is an array with only the selected time, which is not a range time array.
my code:
<DatePicker Dates="new List<DateTime?>{context.StartDate,context.EndDate}" DatesChanged="arr=>DatesChanged(arr,context)" TValue="DateTime?" InputMode="DateInputMode.Date" SelectionMode="DateInputSelectionMode.Range" />

private Task DatesChanged(IReadOnlyList<DateTime?> dates, GetStockInAndOutNoticesInput input) { input.StartDate=dates.FirstOrDefault(); input.EndDate = dates.LastOrDefault(); return Task.CompletedTask; }

Describe the solution you'd like
I hope that an event will be triggered after I select the start time and end time, but I cannot find this event, or there will be a confirmation button at the end of the time range selection for me to To trigger this event,
