Odoo 18 (js): How to extend the native payment_paypal module to activate the PayLater feature?

I am trying to figure out how to extend the js class of the native module payment_paypal, so that the PayLater option, that i have activated in PayPal get activated.

In the native js code in /addons/payment_paypal/.../payment_form.js:

import paymentForm from '@payment/js/payment_form';paymentForm.include({//...//...    async _prepareInlineForm(providerId, providerCode, paymentOptionId, paymentMethodCode, flow) {        if (providerCode !== 'paypal') {            this._super(...arguments);            return;        }        this._hideInputs();        this._setPaymentFlow('direct');        document.getElementById('o_paypal_button').classList.remove('d-none');        document.getElementById('o_paypal_loading').classList.remove('d-none');        // Check if instantiation of the component is needed.        this.paypalData ??= {}; // Store the component of each instantiated payment method.        const currentPayPalData = this.paypalData[paymentOptionId]        if (this.selectedOptionId && this.selectedOptionId !== paymentOptionId) {            this.paypalData[this.selectedOptionId]['paypalButton'].hide()        }        if (currentPayPalData && this.selectedOptionId !== paymentOptionId) {            const paypalSDKURL = this.paypalData[paymentOptionId]['sdkURL']            const paypalButton = this.paypalData[paymentOptionId]['paypalButton']            await loadJS(paypalSDKURL);            paypalButton.show();        }        else if (!currentPayPalData) {            this.paypalData[paymentOptionId] = {}            const radio = document.querySelector('input[name="o_payment_radio"]:checked');            if (radio) {                this.inlineFormValues = JSON.parse(radio.dataset['paypalInlineFormValues']);                this.paypalColor = radio.dataset['paypalColor']            }            // https://developer.paypal.com/sdk/js/configuration/#link-queryparameters            const { client_id, currency_code } = this.inlineFormValues            const paypalSDKURL = `https://www.paypal.com/sdk/js?client-id=${                client_id}&components=buttons&currency=${currency_code}&intent=capture`            await loadJS(paypalSDKURL);            const paypalButton = paypal.Buttons({ // https://developer.paypal.com/sdk/js/reference                fundingSource: paypal.FUNDING.PAYPAL,                style: { // https://developer.paypal.com/sdk/js/reference/#link-style                    color: this.paypalColor,                    label: 'paypal',                    disableMaxWidth: true,                    borderRadius: 6,                },                createOrder: this._paypalOnClick.bind(this),                onApprove: this._paypalOnApprove.bind(this),                onCancel: this._paypalOnCancel.bind(this),                onError: this._paypalOnError.bind(this),            });            this.paypalData[paymentOptionId]['sdkURL'] = paypalSDKURL;            this.paypalData[paymentOptionId]['paypalButton'] = paypalButton;            paypalButton.render('#o_paypal_button');        }        document.getElementById('o_paypal_loading').classList.add('d-none');        this.selectedOptionId = paymentOptionId;    },

In my custom module payment_paypal_custom, if i try to extend this js class using paymentForm.include to override the function _prepareInlineForm in order to add parameters in the sdkURL, the native function of the payment_paypal module will be loaded anyway, so that paypal sdk will be loaded twice. And i can not override complettely this function without calling _super(), because _super() enables the loading of the other payment methods too (Stripe...)!

Any idea how to extend it the right way ?
