Sweetalert does not cancel deletion

Question

I created a deletion system with sweetalert, when clicking delete, it does not cancel the deletion. The language used is PHP without OO and PDO. Could you help me?

Follow the code of the Alert and the button:

<script>
		
		$(document).ready(function(){
			$('.bt').click(function(){
				var th = $(this);
				var id = $(this).attr("id");
				Swal.fire({
					title: 'Are you sure?',
					text: "You won't be able to revert this!",
					type: 'warning',
					showCancelButton: true,
					confirmButtonColor: '#3085d6',
					cancelButtonColor: '#d33',
					confirmButtonText: 'Yes, delete it!'
				}).then((result) => {
					$.ajax({
						url: 'phpAction/delete.php',
						type: 'POST',
						data: {idd:id},
						success: function(data){
							th.parents('tr').hide();
						}
					})
					if (result.value) {
						Swal.fire(
							'Deleted!',
							'Your file has been deleted.',
							'success'
							)
					}
				});

				
			});
		});

	</script>

<button class="btn btn-sm btn-danger bt" id="<?php echo $dados['idUsuario']; ?>"><i class="fas fa-trash-alt"></i></button>
