I wanted to ask

1 – Do translation editorsTranslation Editor Translation editors can approve translations for projects. The GTE (General Translation Editor) and LM (Locale Manager) roles can add new users with the "Project Translation Editor" role that can approve translations for specific projects. There are two different Translation Editor roles: General Translation Editor and Project Translation Editor receive a notification that I have proposed a new translation?
Or that every time I offer a new translation I need to update?
2 – How do I update WordPress, can I add the pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party I translated to the index in Hebrew?
