I want to override the following template from Odoo 18 enterprise source code (specifically I want to override the <t t-out="availableResource['name']"/> and replace it with <t t-out="availableResource['display_name']"/>:

<?xml version="1.0" encoding="UTF-8"?>
<template>
    <t t-name="appointment.resources_list">
        <label for="resource_id" class="mb-1">Make your choice</label>
        <select class="o_resources_list form-select cursor-pointer" name="resource_id">
            <t t-if="scheduleBasedOn === 'resources'">
                <option t-foreach="availableResources" t-as="availableResource" t-key="availableResource_index"
                    t-att-value="availableResource['id']" t-att-data-resource-capacity="availableResource['capacity']">
                    <t t-out="availableResource['name']"/>
                </option>
            </t>
            <option t-else="" t-foreach="availableStaffUsers" t-as="availableUser" t-key="availableUser_index"
                t-att-value="availableUser['id']">
                <t t-out="availableUser['name']"/>
            </option>
        </select>
        <button name="submitSlotInfoSelected" class="btn btn-primary w-100 mt-3">Confirm</button>
    </t>
</template>

The problem is that the template has no id and it is rendered from a js file using renderToFragment:

this.resourceSelectionEl.replaceChildren(
            renderToFragment("appointment.resources_list", {
                availableResources,
                availableStaffUsers,
                scheduleBasedOn,
            })
        );

If it means anything the template is used for displaying the select table drop down list in website restaurant table booking. The file is located at appointment/static/src/xml/appointment_resources.xml and the js file that renders it is at appointment/static/src/js/appointment_select_appointment_slot.js 

How can I inherit this template with no id?
