How to override with mixin my multisafepay credit-card-component js

I’m trying to override one method from the Multisafepay Payment Module.

// vendor/multisafepay/magento2-frontend/view/base/requirejs-config.js
let config = {
  map: {
    '*': {
        multisafepayCreditCardComponent: 'MultiSafepay_ConnectFrontend/js/credit-card-component'
    }
  }
};

So I created my own module / requirejs :

// app/code/Acme/Checkout/view/base/requirejs-config.js
console.log('RequireJS Override');
var config = {
mixins:
    {
        multisafepayCreditCardComponent:
            {
                'Acme_Checkout/js/credit-card-component': true
            }
    }
};

And here is the mixin js file :

// app/code/Acme/Checkout/view/base/web/js/credit-card-component.js
define([
    'jquery',
    'mage/translate',
    'Magento_Customer/js/customer-data',
    'Magento_Checkout/js/model/quote',
    'multisafepayCreditCardComponentLib'
], function (
    $,
    $t,
    customerData,
    quote,
    multisafepayCreditCardComponentLib
) {
    'use strict';

    console.log('Override mixin');

    var mixin =
    {
        /**
         *
         * @param paymentRequestData
         * @returns {{template: {settings: {embed_mode: boolean}}, amount: number, currency, customer: {country, locale}}}
         */
        getOrderData: function (paymentRequestData) {

            console.log('msp vendor 2');

            return {
                customer: {
                    locale: paymentRequestData.locale,
                    country: quote.billingAddress().countryId
                },
                currency: paymentRequestData.currency,
                amount: paymentRequestData.cartTotal * 100,
                template: {
                    settings: {
                        embed_mode: true
                    },
                    "payment_form": {
                        "inputs": {
                            "background": "#161616",
                            "color": "#a7a7a8",
                            "font": {
                                "size": 14,
                                "placeholder_color": ""
                            },
                            "border": {
                                "color": "#cccccc",
                                "radius": 0,
                                "box_shadow": 0
                            },
                            "label": {
                                "color": "#212529",
                                "size": 16
                            }
                        }
                    }
                }
            }
        }
    };

     return function (target) { 
        return target.extend(mixin);
    };
});

The problem is : the requireJS is correctly read (I get the ‘RequireJS Override’ log). But my console.log(‘Override mixin’); is never triggered. I don’t know what is wrong here. Can someone help ?
