Load SQL database saved MS word document to Syncfusion Document Editor

Model.Attchment contains the byte[] of the document. It comes to the client side with my script, but not displayed in the Document Editor.

This is the script I’m using :
`
var base64Content = “@Html.Raw(Convert.ToBase64String(Model.Attachment))”;
var documentEditor = new ej.documenteditor.DocumentEditor({
isReadOnly: false
});

documentEditor.appendTo('#documenteditor_titlebar');

// Function to load the document into the Document Editor
function loadDocument() {
    documentEditor.open({
        document: {
            fileContent: base64Content,
            fileName: "document.docx",
            fileType: "Docx",
        }
    });
}

// Load the document when the DOM content is fully loaded
document.addEventListener("DOMContentLoaded", function () {
    loadDocument();
});
