How to display menu on toolbar for TinyMCE4

I need to add following code to display menu on tool bar for TinyMCE4 but I don't witch file I need to modify.
Is there any one know where I need to add?

    <script type="text/javascript" src="<yourinstallationpath>/tinymce/tinymce.min.js"></script>
    <scripttype="text/javascript">
    tinymce.init({
    selector:"textarea",
    language :"en",
    plugins:[
    "advlist autolink lists link image charmap print preview anchor",
    "searchreplace visualblocks code fullscreen",
    "insertdatetime media table contextmenu paste youtube"
    ],
    toolbar:"insertfile undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image youtube"
    });
    </script>
    
    <formmethod="post"action="somepage">
    <textareaname="content"style="width:100%"></textarea>
    </form>

Any advice would be greatly appreciated.

That appears to be for a custom area on a form; that is not part of the standard Dolphin init file.

If you wan the menubar to appear, it is menubar : true
