Advance Select Keeping Previous Options how to remove them and add new options

[PranayHalder]

const pickupSelect = window.HSSelect.getInstance('#instantPickupSelect');
const locationSelect = HSSelect.getInstance('#location_id');
locationSelect.on('change', (val) => {

	$.ajax({
		url: route('fetchPickDrop'),
		method: 'POST',
		data: {
			location_id: val
		},
		dataType: 'JSON',
		headers: {
			'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
		},
		success: (response) => {   
			if (response.success == true) {
			response.pickDropLocations.forEach((location) => { 
				  pickupSelect.addOption({ title: location.name, val: location.id.toString() });
			}); 
			}
			
		}
	}); 

});

This is my code , i want to dynamically add new options according the the location but if keeps all data from the previous options , how to fix it , there is no method mentioned about clearing old options in the docs
