The page is refreshing when message sent ? e.preventDefault() is not working

I created a chatbot in which, first, I’ll receive a response. In the form, there is a last field that has a value, and I want to send that value as a user message. The bot is working fine, but when I click on ‘chatsubmit,’ it refreshes the page. e.preventDefault() is not working because it is false, but without false, I can’t send the values.

const submitForm = async (e, val) => {
    if (e) { e.preventDefault(); }

    if (!conversationId) {
        console.error('conversationId is not set.');
        return;
    }

    document.querySelector("#chat-submit").disabled = true;

    let x = document.forms["form-feedback-data"]["message"];
    let message = val || x.value;

    console.log('Submitting message:', message);

    // Send user message to API
    await sendToApi(conversationId, "user", message);

    if (message !== "") {
        let aud = new Audio("https://backend.aiduals.com/assets/userMusic.mp3");
        aud.play();

        // Display user message in chat window
        let userDiv = `
            <div class="aidual_chatbot_wrap">
                <div style="display: flex; align-items: center; justify-content: end;">

                                    </div>

I want to submit the form first, then receive the value as user input, and the page should not refresh when I send the message.
