Hi guys, i work on odoo 16 and i want to custom widget step by using FieldHtml in module web_editor. My code update from odoo15. However, i declare variable like 
var FieldHtml = require('web_editor/js/backend/field_html')

but it's does not work, I need some idea, thank a lot!

My code is here:

odoo.define("report_odoo.ReportPreview, function (require) {
    "use strict";

    const FieldHtml = require('@web_editor/js/backend/field_html');
    var field_registry = require("web.field_registry");
    var core = require("web.core");
    var rpc = require("web.rpc");
    var session = require("web.session");
    const { Dialog } = require("@web/core/dialog/dialog");
    var translation = require('web.translation');
    var _t = translation._t;

    var ReportPreview = FieldHtml.extend({
        //logic
    });

    field_registry.add(", EVReportPreview);

    return ReportPreview;
});
