How to create Factory Functions instead of using Classes

Instead of classes, I want to use factory functions.

Original code with classes:

export class MyProject {
    constructor(title, description, dueDate, priority) {
        this.title = title;
        this.description = description;
        this.dueDate = dueDate;
        this.priority = priority;
        this.todos = [];
        this.projectIndex = null;

        this.expandContent = () => expandContent(this);
        this.deleteCard = () => deleteCard(this);
        this.addTodo = (todoText) => {
            this.todos.push(todoText);
            this.expandContent();
        };
    }
}

I tried using factory functions:

export const MyProject = (title, description, dueDate, priority) => {
    let todos = [];
    let projectIndex = null;

    const expandContent = () => expandContent(this);
    const deleteCard = () => deleteCard(this);
    const addTodo = (todoText) => {
        todos.push(todoText);
        expandContent();
    }

    return {title, description, dueDate, priority, todos, projectIndex, expandContent, deleteCard, addTodo}
};

I've acknowledged, that this is not necessary in factories, I'm not really sure how not to use them in expandContent and deleteCard functions
