How to hide buttons

Here's an example of hiding a button in the toolbar in three different ways.

Code

<!-- element -->
<textarea id="entry">...</textarea>

<!-- call -->
<script>
Redactor.add('plugin', 'myplugin', {
    start() {
        // 1) remove from a plugin
        this.app.toolbar.remove('list');
    }
});

let app = Redactor('#entry', {
    plugins: ['myplugin'],
    // 2) hide with setting
    toolbar: {
        hide: ['deleted']
    },
    // 3) change toolbar layout
    buttons: {
        toolbar: ['add',  'html', 'format', 'bold', 'italic', 'link', 'image']
    }
});
</script>
