JQuery. I have to access an element in html by using this keyword in a click event, but for some reason it does not work

Question

My problem is that this key word does not give me the html element. I'm using it in a click event.

It simply does no react when i click and thats all, no errors no nothing.

JS Code:

$(document).ready(function () {

    $('.question-toggle-button').click(() => {
        $(this).addClass("question-active");
    });
});

Also the HTML:

                    <div class="question">
                        <div class="question-top-row">
                            <div class="question-top-left">
                                <div class="question-number">
                                    01
                                </div>
                            </div>
                            <div class="question-top-center">
                                <div class="question-question">

                                </div>
                            </div>
                            <div class="question-top-right">
                                <div class="question-toggle-button">
                                    <img src="./img/cross.png" alt="">
                                </div>
                            </div>
                        </div>
                        <div class="question-bottom-row">
                            <div class="question-answer">
