Uploading Image with Bio to PHP via AJAX jQuery

I want to upload User images via AJAX to PHP Database. I tried multiple tutorials and other examples but nothing worked for my code. The codes work when used without AJAX but since I don't wish my users to see the upload page and stay on the same page that's why the thought of adding AJAX to the code. So have been trying this code for the past few hours but nothing worked in my favor. The files are not getting uploaded nor the data in the database is getting updated.

file: test.php

<script> 
  function triggerClick(e) {   document.querySelector('#profileImage').click(); }
     function displayImage(e) {   if (e.files[0]) {
         var reader = new FileReader();
         reader.onload = function(e){
           document.querySelector('#profileDisplay').setAttribute('src', e.target.result);
         }
         reader.readAsDataURL(e.files[0]);   } }
         
                $(document).on('click',"#UploadImage", function(){
                     var fd = new FormData();
                 var profileImage = $('#profileImage')[0].files[0];
                 //fd.append('profileImage',profileImage);
                var bio = document.getElementById( "bio" ).value;

                $.ajax({
                            url:"include/Upload.php",
                            method:"POST",
                            data: fd,
                             contentType: false,
                             processData: false,
 
                                success:function(data){
                                        alert(data);
                                    if(data == "Login Successful") {
                                        }
                                    else {
                                        alert(data);

                                    }
                                }
                    })       
});  
</script>
