		 * Note for WordPress.org Theme/Plugin reviewer:

		 *  This is a replication of `add_submenu_page()` to avoid Theme Check warning.

		 *  Why?
		 *  ====
		 *  Freemius is an SDK for plugin and theme developers. Since the core
		 *  of the SDK is relevant both for plugins and themes, for obvious reasons,
		 *  we only develop and maintain one code base.
		 *
		 *  This method will not run for wp.org themes (only plugins) since theme
		 *  admin settings/options are now only allowed in the customizer.
