You could use JSOM to get the attachement files.

Sample script:

<script type="text/javascript" src="/SiteAssets/jquery-3.4.1.js"></script>
    <script type="text/javascript">
        function getListItemAttachements() {
            //replace the list and id dynamically
            getAttachements("Test", 1);
        }
        function getAttachements(listName, itemID) {
            var attachmentFiles;
            var ctx = new SP.ClientContext.get_current();
            var web = ctx.get_web();
            var attachmentFolder = web.getFolderByServerRelativeUrl('Lists/' + listName + '/Attachments/' + itemID);
            attachmentFiles = attachmentFolder.get_files();
            ctx.load(attachmentFiles);
            ctx.executeQueryAsync(function () {
                for (var j = 0; j < attachmentFiles["$2_1"].length; j++) {
                    var file = attachmentFiles.itemAt(j);
                    console.log(file.get_name());
                }

            }, function (err) {
                console.log(err);
            });
        }
    </script>
    <input id="Button1" onclick="getListItemAttachements()" type="button" value="button" />
