Fix dropzone.js to allow it to work for front end wordpress posting script

I am looking for a developer to fix the issue with dropzone.js for my front end WordPress posting script. The specific issue I am experiencing is that it is not uploading files. The issue seems to be related to dropzone trying to upload files before the post is submitted but wordpress doesnt process anythign until a post is submitted. I dont care if you make dropzone just a fancy uploader, provide a similar solution, or if you can make dropzone work as intended I just need users to be able to upload files and then upload more before submitting.

Requirements:
- Experience with dropzone.js and WordPress
- Familiarity with the latest version of WordPress
- Ability to troubleshoot and fix issues related to file uploading

Here is the relevant code. If you see the issue. Let me know and I'll pay you to resolve it. I'm not going to share file access and deal with a ton of debugg on this.

function usp_enqueue_scripts() {
global $post;
if (is_a($post, 'WP_Post') && has_shortcode($post->post_content, 'users-submit-posts')) {
wp_enqueue_editor();
wp_enqueue_script('dropzone', 'https://unpkg.com/dropzone@5/dist/min/dropzone.min.js', [], false, false);
wp_enqueue_style('dropzone-css', 'https://unpkg.com/dropzone@5/dist/min/dropzone.min.css');
}
}
add_action('wp_enqueue_scripts', 'usp_enqueue_scripts');

<div id="dropzone" class="dropzone"></div>
<input type="submit" name="submit-post" value="Submit Post">


<script type="text/javascript">
Dropzone.autoDiscover = false;
var myDropzone = new Dropzone("#dropzone", {
url: "/wp-admin/admin-ajax.php",
autoProcessQueue: false,
addRemoveLinks: true,
maxFiles: 10,
acceptedFiles: "image/*",
params: {
action: 'handle_dropzone_upload'
}
});

document.getElementById('usp-form').addEventListener('submit', function(e) {
e.preventDefault();
var formData = new FormData(this);
formData.append('action', 'usp_handle_submission'); // Specify the action name

myDropzone.files.forEach(function(file) {
formData.append('user-submitted-cover-photos[]', file);
});

jQuery.ajax({
url: '/wp-admin/admin-ajax.php',
type: 'POST',
data: formData,
processData: false,
contentType: false,
success: function(response) {
console.log(response); // Debugging line
if(response && response.success && response.data && response.data.redirect_url) {
window.location.href = response.data.redirect_url;
} else {
console.error('Unexpected response:', response);
}
},
error: function(jqXHR, textStatus, errorThrown) {
console.error(textStatus, errorThrown);
}
});
});
</script>
