Simply put: this plugin gives the Editor role access to edit “theme options”, which includes:
<ul>
<li>Appearance > Widgets</li>
<li>Appearance > Menus</li>
<li>Appearance > Customize if they are supported by the current theme</li>
<li>Appearance > Background</li>
<li>Appearance > Header</li>
</ul>
Instead of adding this capability by hand on each client site, just install and activate this plugin—it keeps your <code>functions.php</code> file clean, and keeps this type of functionality where it belongs.
The capability is added to the role once (on plugin activation) and removed when the plugin is deactivated.

The Restore Customizer Menu for FSE Themes plugin adds a “Customize” menu item under the Appearance section in the WordPress admin panel. This is particularly useful for Full Site Editing (FSE) themes like Twenty Twenty-Five or Twenty Twenty-Three, where the classic Customizer is not directly accessible. The plugin allows easy access to settings such as favicon, site title, and other theme options.
