Alpine JS global function not defined

Question

I am using Alpine JS store() to make a global function available to toggle a modal status.

Module:

export default () => ({
    /**
     * @property isOpen - controls the state of the Contact Form Modal
     */
    isOpen: false,

    open() {
        this.isOpen = true
    },

    close() {
        this.isOpen = false
    },
});

Then I use it like:

import modalContactForm from './alpine/modal-contact-form';

// Alpine.store sets data for GLOBAL usage
Alpine.store('modalContactForm', modalContactForm);
Alpine.start();

And with this HTML:

<button x-data @click="$store.modalContactForm.open()"></button>

But I get:

Alpine Expression Error: $store.modalContactForm.open is not a function

And I don't know how to debug this situation.

Interestingly, if I pass the object directly into Alpine.store(), it works.

Alpine.store('modalContactForm', {
        isOpen: false,
    
        open() {
            this.isOpen = true
        },
    
        close() {
            this.isOpen = false
        },
    });
Alpine.start();

In the external module file export the store as a simple object, not as an anonymous function:

const modalContactForm = {
    /**
     * @property isOpen - controls the state of the Contact Form Modal
     */
    isOpen: false,

    open() {
        this.isOpen = true
    },

    close() {
        this.isOpen = false
    },
}

export default modalContactForm
