Magento 2 Adding Wysiwyg to Custom Tab in Catalog_Product_New

Question

I have successfully added a custom tab in the product admin page, and can save it in the database and display it on the frontend, however I am wanting to add a Wysiwyg editor for the body content and I can't seem to get it to display properly

Here are code examples so you can better understand my problem:

Inside my di.xml

 <?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

                </item>
            </argument>
        </arguments>

</config>

Inside DataProvider/Product/Form/Modifier/CustomFieldset.php

            ],

    ];

}

Inside the getTextAreaFieldConfig function I am trying to call the Wyiwyg form element but it does not appear.

Any advice on how I can do this?
