I can’t change the text in one calendar message

I need to change one message generated by the calendar to another, I mean the message “There are no upcoming events.”. I tried with the below JS, but it didn’t work. Please help – how can I change the content of this message?

document.addEventListener("DOMContentLoaded", function () {
    const updateEventMessage = () => {
        const noEventsMessage = document.querySelector(
            ".tribe-events-c-messages__message-list-item[data-key='0']"
        );

        if (noEventsMessage && noEventsMessage.textContent.trim() === "There are no upcoming events.") {
            noEventsMessage.textContent = "My NEW text.";
        }
    };

    const observer = new MutationObserver(function (mutationsList) {
        mutationsList.forEach(function (mutation) {
            if (mutation.type === "childList") {
                updateEventMessage();
            }
        });
    });

    const targetNode = document.querySelector(".tribe-events-c-messages__message-list");
    if (targetNode) {
        observer.observe(targetNode, {
            childList: true,
            subtree: true
        });
    }

    updateEventMessage();
});
