Magento 2 : Remove Confirmation Popup when deleting products from the mini cart

I created mixin. When I comment out confirm({}) in core sidebar.js it works as expected, but my mixin doest work. It does’t remove popup.
requirejs-config.js:

var config = {
    config: {
        mixins: {
            'Magento_Checkout/js/sidebar': {
                'Magento_Checkout/js/sidebar-mixin': true
            }
        }
    }
};

Created js/sidebar-mixin.js

define([
    'jquery',
], function ($) {
    'use strict';

    return function (widget) {
        $.widget('mage.sidebar', widget, {
            _initContent: function () {
                this._super();
                var self = this,
                    events = {};

                this.element.decorate('list', this.options.isRecursive);

                /**
                 * @param {jQuery.Event} event
                 */
                events['click ' + this.options.button.close] = function (event) {
                    event.stopPropagation();
                    $(this.options.targetElement).dropdownDialog('close');
                };
                events['click ' + this.options.button.checkout] = $.proxy(function () {
                    var cart = customerData.get('cart'),
                        customer = customerData.get('customer'),
                        element = $(this.options.button.checkout);

                    if (!customer().firstname && cart().isGuestCheckoutAllowed === false) {
                        // set URL for redirect on successful login/registration. It's postprocessed on backend.
                        $.cookie('login_redirect', this.options.url.checkout);

                        if (this.options.url.isRedirectRequired) {
