I try to set current date for datepicker as default but can't get any results:

DatePicker::make()->name('date')->label(__('Date'))->time24Hr(true)->allowInput(true)->default(HOW?)

DatePicker::make()->name('date')->label(__('Date'))->time24Hr(true)->allowInput(true)->default(HOW?)

There are no docs on this topic.
