重置浏览器通知权限？

Question

如何使用Java重置通知权限？我为此启用他们：

var prm = Notification.permission;
if (prm == 'default' || prm == 'denied') {
                Notification.requestPermission().then(function (permission) {
                    if (permission === "denied") {
                        $($('#notification-toggle')).prop('checked', false)
                        $('#notification-toggle-callback').html('Notification permissions are blocked.')
                    } else {
                        var notification = new Notification('Test Notification', {
                            icon: 'https://jailibrary.github.io/images/favicon/favicon-96x96.png',
                            body: 'Hey there! Notifications are now enabled.',
                        });
                    }
                });
            }

我希望这样，如果用户允许通知，但后来决定禁用它们，我将如何重置权限？谢谢
